I needed to glue a knife handle onto a hidden tang knife, and at first I tried 5 minute epoxy. It got crooked and I couldn't straighten it and ended up having to yank the blade out at the last minute. I cleaned it all up and looked for 30 minute epoxy. This was the only one I could find, but it works great, you get a ton of glue for the price, the tensile strength is very high, and best of all, you get a lot of time to make adjustments to your work before it gets.

A little instructions would help. Initially I added the plastic tip in the back. No go. Finally tried on front and they flew better. Go a good 20 feet before going to ground. But perfect distance for little ones These were bought for our Twp kid fest this weekend. I am sure the little ones will love getting these. For the price it's perfect

Plugged into both a computer and a wall outlet. Both times it started charging and showed a green light. Shortly after, it began flashing blue and stopped charging. I tried it with an OtterBox and without an OtterBox. Tried repositioning it, tried changing the cord it came with, and tried a different outlet. Same result each time. Really bummed about this because it looked nice on my desk at work.
