    It’s really cool to have water filtration I’m a portably device like this. Fun to use and hits hard 🙂

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

    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.

    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!

    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!

    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.

    It works great just ordered a second one!

  18. Robert (verified owner)

    So far so good. Just received it today but I’m extremely satisfied as of right now. Haven’t tried a cartridge yet but tried it with some distillate and the hit was amazing. Hopefully there won’t be any issues in the future otherwise this is definitely worth the money.
