    The best vape device I own love the bubbler just wish there was a water line marking. But overall happy. Also ordered extra cartridges for wax i have yet to use.

  14. Jbrown (verified owner)

    Just needs a little more glue at the seem of the tank and a cleaning kit add on would be nice.

  15. Anonymous (verified owner)

    I’m satisfied with how it works but when using dab tool you have to clean more often

  16. William Priester

    Good. & Easy to use, & clean.

    My favorite at home vape “rig”. Exactly what I was looking for. Customer service is amazing, mine had a defect, got my new one in 3 days!

  20. Anonymous (verified owner)

    Wonderful, easy to use, be sure to clean often!

  21. John Donnelly

    Great concept and product – one design flaw is the glass bubbler needs better protection when knocked over or dropped. I have broken two glass bubblers so far and it is simply a pain to get replacements. Perhaps a shield or cone to protect the bubbler – something from silicone should work – even a slip on sleeve.

  22. Fatima

    Reaching out because I was a bit curious on how you know when the battery is low? Does it just die on you? Everything about this device is amazing bought it yesterday and this is crazy!! I’m still hitting and it’s like a mini travel device that you can hit on the go

  23. Charles (verified owner)

    Nice water vape pipe to mellow out heat.

  24. Lisa M. (verified owner)

    This bubbler is the best investment I’ve made. It is so easy to use but it delivers the most concentrated but very very smooth. The only thing is you have to keep the bowl clean and it doesn’t fail.

  25. Peter B. (verified owner)

    As advertised, works right out of the box, a much safer way to vape with a stronger taste profile than a pen can offer.

  26. James (verified owner)

    Works great! Game changer for Vape THC. My order was processed immediately and shipped to me within days!

  27. William Robinson (verified owner)

    Amazing device, have recommended it to a couple of friends and they plan on purchasing one of their own. The bubble makes a huge difference with the carts, and the wax coil is also pretty impressive.

  28. William R (verified owner)

    This device is amazing, worth every penny. I even sold a buddy on it, plans on purchasing one next week. Thank you for your hard work. Any chance I could get some free coils for the referal? lol

  30. Leslie Finch

    What a kick ass little device took me a minute to figure it out, but once I did wow I love it.. And the bubbler love it when you add water it makes every rip so much smother.. Good investment definitely gonna pass the word I love new toy!!!💋

    Another better than a small pen that gets too hot…very nice.

  35. Thomas Norris

    I love this device. I’ve always wanted a bubbler that deals in carts and concentrates. Amazing job Hamilton team!

  36. Hippy Dude

    Wow! This device ROCKS! I’ve owned a lot of different dab rigs and vape paraphernalia but this one is the best. For carts or concentrates, it’s the best I’ve seen and easy to carry.

  37. Justin (verified owner)

    Ver ver nice

  38. Dazz (verified owner)

    KR1 is great for use with carts, and its not bad with concentrates as long as you pre-heat and don’t put too much in, and you have to hit very very slow and soft – if you hit hard it will result in most of your concentrate flying up all over and sticking to side of the main case. if you don’t pre-heat and hit real slow you won’t get much of a hit. I love my KR1 – worth the money – i was a bit concerned however that on the device instructions it has a warning that the device contains chemicals known to cause cancer, birth defects, or other reproductive harm. That warning was not on the website description when i ordered it. I think that warning should be on the website so people know this before ordering. I almost sent mine back due when i read the warning, but im old and probably won’t live much longer anyhow so Im throwing caution to the wind,

  39. dylan weber (verified owner)

    love the product, worth the price

  40. Danial (verified owner)

    My first vape bubbler so I don’t have a lot of experience but I do love everything about the KR1. Bigger hits less heat. Fun to use. Dig the leds!

  41. Matthew P. (verified owner)

    Very freshing way to hit a cart! Cool lighting effect and hits hard! Cannot wait to teat her our on some concentrate.

  42. Suraj (verified owner)

    The seal is properly done with the carb. Not many products on the market that can compare. I’m giving a 4 because I would’ve preferred the option to use the device at a voltage below 3 volts or the option to choose a battery which could support that function. Cleaning is just a bit tedious but when is it not. After a couple of weeks of consistent use I want to say: Great device, thoroughly satisfied, and happy with the purchase.

  43. Joseph P. (verified owner)

    If you want a bubbler for your cart or just want to be able to dab on the go this is the device you want!!!

  44. Scott H. (verified owner)

    Product seems to do what it promises. Takes away the burn but still has to be used on the low setting. Shipping was fast. It seems like it’s a good quality item. So far so good!

  45. Donna C. (verified owner)

    The KR1 really creates smooth hits.

  46. Timothy Pourner (verified owner)

    Nice and smooth love it

  47. Timothy Rush

    I got this from a local shop as I was looking for something that would be unique and offer a different experience, and honestly I’m super impressed! Contrary to first glance, it’s actually very easy to clean and use. And the vape from it is so smooth and really preserves the flavor. It’s so good that even my boyfriend, who doesn’t even like vaping all that much, got one for when he does it on occasion.

  48. John Paul

    So far so good! Good volume, and really smooth hits.

    Device is great. A real simple portable mini rig if you would. Had an issue with mine hitting within a year and Hamilton’s customer service got back to me within 24 hours and offered a replacement to be sent out within the work week. Top notch customer service. Customer for life

  52. Jim

    Love this thing! Hits way harder than regular pens. The wax coil part is a little awkward to use. Cleaning is pretty simple with long q-tips/alcohol. There should be an auto shut off added to it.

  53. Benjamin (verified owner)

    Super cool device. Works as intended.

  54. Corey jeffrey

    i agree with one of the other comments. I wont lie i got my ass rocked on that first hit. I smoke a half cart a day. So cleaning sucks. Maybe dishwasher safe for us hard chilling stoners. While the battery charges. The coil for wax broke like a week into owning it. I love the breakdown. Kinda wish the plastic was glass. Over all very decent product.

  55. Christopher (verified owner)

    It’s awesome,hit hard great!

  56. Brian D. (verified owner)

    For the price it works. The concept is wonderful, with the carts it seems to be a hit or miss on it’s effectiveness. The wax/oil option rips, it will get you past where you were trying to go, the bubbler makes the taste perfect. I’m looking forward to the next upgraded model!!

  57. DrtyDave (verified owner)

    Just received my KR1 and let me say it is with out a doubt one of the finest vaping rigs for dabs, tons of clouds and a great high. It is worth every penny

  58. David Parker

    This allows you to take deep hits, on a low setting, which adds an incredible complexity of flavor to your medicated state of mind. I’m using a 510 of Banana Cream and it’s an entirely different experience. I’m waiting for the next generation, seriously this is a game changer.

    The only flaw in the product is the plastic housing, which should have been made with glass as it is VERY hard to clean the vapor residue buildup.

  68. Chris Picou (verified owner)

    All I can say is Thank You God. This baby right here is THE TRUTH!!! Carts and Extracts? What!!! Shut yo mouth!!! I’m only talking about the best of the best. Do a dab or do a cart. You make the call and you won’t go wrong. Trust the 50 Year Old Stoner I ain’t got no reason to lie because I’m high.

  69. Gabby Leach (verified owner)

    I recently got into dabbing and the KR1 is great for that. Doubles as a cartridge vape and both work wonderfully.

    Woah…. This thing is Amazing. I wish the voltage could be adjusted a little bit lower. But all in all this is a 10/10

  77. Davey Grohlton

    After months of use, I will give a review. There is a lot I like about this product and some things I do not like. The glass piece is nice, but the plastic piece it goes into is a headache. As you use your vape carts in this product, whatever resin(terps,oil,whatever) builds up on the inside of the plastic piece. Using alcohol becomes a must in order to get it clean, but even then a q-tip is still needed to scrub the insides. Good luck fitting a q-tip all the down into there too… One side is deeper than a q-tip is long, so you will more than likely have difficulty. I use tweezers to lengthen the q-tip so it can reach all the way down to scrub it. I found cleaning it DAILY to be the only way to keep the flavors nice and it working properly. If you are using D8 carts, DEFINITELY clean it daily or else that stuff becomes super harsh. Battery life is good and the bubbler part does really help with D8 carts, but I wish it was bigger. Cleaning it is a little bit of a PITA because its small. You cant just throw some alcohol in it and shake it around…. it HAS to be scrubbed with a q-tip too to remove that film off the inside. If you don’t mind daily cleaning, then this product is very nice.

    Such an amazing product and I can’t wait to put it to use

    I love this rig. My son took the first one I ordered so I immediately had to order one again for myself. I own a lot of different smoke apparatuses this is hands down the best.

    I have two of them and one is on me at all times.

  83. Anonymous (verified owner)

    if this had an optional glass instead of plastic top shell, it would truly be a 10/10 device, i had a bit of trouble getting it to fire at first, turned out some of my carts with a floating 510 pin didnt make good connection until i pulled them out a little. my other complaint is its too easy to block the air inlet with your finger while pressing the fire button. the light is also very bright, i just put a tiny piece of electrical tape over it. all in all a highly recommended device.

  84. Cara A. (verified owner)

    Loving the KR1! Comes in a beautiful, inky blue colored box with a gold Kraken design and lettering. Very easy to assemble and gives huge, tasty hits that are super smooth!

  85. Jason Z. (verified owner)

    Easy to set up and charge. Great product, I would recommend to anybody. It hits great, looks cool, and easy to store. Can’t say enough about it! If you’re reading comments to decide, just but it, definitely worth the money!

  86. Tom Hanks

    Works good. Been using for D8THC carts. Watch out for cart clogs as they can create back pressure that will shoot bubbler water onto cart side of plastic piece and into your mouth. Also, clean daily for best flavor. Def clean in between switching carts too as the water picks up the terpene flavor profile of whatever your smoking…. Found that out on Pineapple Express lmao. The carb hole is located in a junky spot IMO. It can be finicky to cover correctly and press the power button at the same time. Clearly you should handle both with your thumb, but the clear plastic part above the carb sits slightly higher than the metal battery side, so when you go the press the button and cover the carb at the same time, if your thumb gets onto the clear plastic piece, it interferes with your ability to properly use the carb. I find the “ridge” left by the clear plastic piece and always make sure my thumb is below it and that allows me the create a “closure” on the carb hole. If thumb goes onto clear plastic piece, the carb does not fully seal… or something like that and it usually causes the cart to clog. I like everything about this cart but the carb location. It just feels like it was added last second and it is the weak spot on this device.
