    Very well built, compact, discrete, easy to use, and come on its a butter fly vape 😝 🤘💨👍

    the butterfly is a unique battery. The only reason i didn’t give it a full 5 stars is mainly because of 2 things. The first being that after a day of use my nail had made an imprint on the battery. The second thing is that everytime i try to do tricks or open and close the butterfly it seems to always blink blue. I believe it is supposed to do this whenever the cart is being installed. However, it seems when you fidget with it too much it keeps blinking blue. Not sure if its due to the way the cartridge is connected but both of these reasons haven’t affected my enjoyment from the item.

    i like the battery its cool but it is very hard to hit cuz if you dont have the metals together right it dont hit at all

  11. Verified Buyer (verified owner)

    This thing is pretty damn cool. It functions perfectly normal but lets be real we all bought it because its a butterfly knife pen. Cool factor 10/10 and everyone I hand it to thinks its awesome.

  12. Verified Buyer (verified owner)

    Was kinda skeptical at first but was a really good quality, no problems would buy again

  13. Brett (verified owner)

    It’s OK. As expected.

  26. Tristan Hemans (verified owner)

    It’s a very interesting device

  27. Brett (verified owner)

    Quick and easy shipping. Battery is made super well – arms have suitable play in them, satisfying to fidget with, and works well with all cartridges I’ve tried. Only annoyance is the lack of a pre-heat function, but just fire the device a bit and same thing. Very happy!

  28. R P (verified owner)

    Better than a fidget spinner.

  29. Darrell (verified owner)

    It’s a fidget spinner that you can vape from. What more could you want?

  30. William (verified owner)

    So Cool!

  34. James (verified owner)

    Love this battery. I saw this drop and I knew I had to grab me one. I got the gold butterfly battery and as a fan of butterfly knifes and 510 batteries this takes the cake and I’d say this was a great purchase. I’ve made multiple orders at Hamilton devices and yeah good atuff

    Very cool battery, fun to flip and stab your friends with.

  38. Daniel Hernandez (verified owner)

    Just got it earlier today and so far im loving it! Hits decent and is entertaining to flip around. Only complaint is when you close it you can hear the glass of the cart hit the metal frame, I cut out a thin piece of foam with adhesive and lined the inside of it and now I can flip it around and not worry about maybe cracking the glass. I got lucky and had this stuff lying around so I resolved it but I can see how it could be an issue if you risk breaking carts by closing it.
