Well I liked the damn thing... until it just bellied up and died. Only light modeling use like cleaning scuff off models ... and tonight it just died. Disappointed.

This is a clever idea and the tool comes with a lot of accessories. The instructions don't tell you much about how to use it - I suppose that would be by experimenting. In fact, the instructions say to lock the bit in with the enclosed wrench, but the tool I received had a friction collet and no wrench - though it held the bit just fine. Look at the photos after the listing to see all the bits and templates it comes with. I had hoped to use this to ID my tools, but the tiny motor really doesn't have enough power to make a sufficient mark. I can see this being a great tool for the jewelry maker though, or perhaps other delicate crafts. I don't know where you would buy extra bits as there is no reference in the enclosed literature. There is also no additional listings for this company on Amazon. I'm sure these tiny bits are sold somewhere, but it would be nice not have to go searching for them. So while this is not good for my intended purpose, I'm sure it will find a use for other uses.

I like this engraving pen and it have good power to work at least for simple engraving. I am completely confused because no manual or guide to use the bits. I just use the large one and no issues so far. Seems to be a good set but I don’t have any experience engraving and with no bits instructions is really confusing. I try change gear but only shut down whenever i try change speed. I will keep playing with this until I get figure it out. I guess this is reccoemnded for people who knows how to use this device bits or stick to the main bit and use it for general purpose.
