Electric Engraving Pen, HARDELL Engraver Tool 37000RPM, USB Cordless Engraving Machine for Artists&DIYers, Portable DIY Rotary Engraver for Jewelry Wood Glass Stone Carving

Solid little engraving pen. I use it for writing on copper plant tags, does a fine job for my purposes. Battery life seems to be pretty long as well. Pen shape makes it much easier to control vs. writing with a Dremel.

Very adequate and worth the purchase if you actually need it. More powerful than the other pen engravers I have used but the battery life is short. Plus you have to take the pen apart, take out the battery, and carefully position the battery just so in its own little charging cradle for it to charge properly. Also, you are required to use a very tiny, very thin, and very easily lost hex key to change out and secure the bits. It's a pretty good pen engraver. Not super, but pretty good.

Amazed how it works now the family wants one that’s I ordered another one wouldn’t give back to me

This is a very handy tool that performs as advertised. It is compact and comes with a charger for the included rechargeable battery. Excellent for detail work.

Tiene mucha fuerza y es justo lo que necesito aunque no se fija

Total crap! THeir ads all show amazing designs done on stones. I tried to engrave a simple design on a stone I picked up at the beach. Using one of the bull-nose styluses. Within 45 seconds -- NO exaggeration -- the bullnose nib had been ground down to nothing and I had a rough pointy end that was useless for everythng else. I was NOT pushing hard. I watched the videos to make sure I was using the instrument right. Maybe it's good for other surfaces, but stones -- NO WAY!

It is difficult to etch with— not easy to keep stable enough for anything but scrawled letters. Plus, if your fingers slip down to the tip, it’s quite dangerous.😳

Nice engraving pen that works well. Can’t give a 5 because there are no instructions for the various size engraving heads that come with the pen.
