Uolor USB Rechargable Engraving Pen with 42 Bits, Mini Electric DIY Engraver Cordless Rotary Tools Portable Engraving Tool for Jewelry Wood Metal Stone Plastic Glass Etching

Full 5 stars from me. I use it often and it works well. Very pleased with the product. I keep it plugged in (if I can) when using to extend the charge time. Seems like under heavy use with a full charge it runs for about 18-22 minutes without having to be charged. I do not know if it should last longer than that on a single charge however for what I use it for - engraving an occasional name in wood, it’s plenty to do that and the charge time has not been an issue. Works great with lots of bit options-easy to change bits. It’s a keeper for sure for my application.

Bit holder too small size do not match with all the bits, couldn't plug in even twisted out the secure

I was looking for small drill bits and the rest was just a bonus. This really is a neat little tool to have. It works great and I haven't had an issue. Im learning to engrave,lol.

not too sturdy, light use only

I bought each of my sons this item as a Christmas gift and they both loved it. Very versatile, many uses.
