DIYARTS 105pcs Electric Engraving Tool Kit, Micro Engraver Etching Pen, Cordless Rotary Tool, USB Rechargeable Grinder Polishing Machine for Glass Wood Metal Stone Plastic Nails Jewelry, Black

This pen always needs to be connect to a power supply it does not have a built in battery, The button lock is too big and gets in the way of holding the device. I guess one gets for what they paid for. If you buy one of these just make sure you buy a USB extension cable or an external power supply like the ones used for phone back-up power supply for easier manoeuvrability. I would give it three stars.*.*.*.

Works well and corresponds to the given data.

I guess u get what you pay for the power lead connection is bad always turns off.If to much pressure is applied it stops, it don't take much to cause it to stop very more instruction too poor packaging too

Left it in my shed

This item is low quality and does NOT work as advertised.It has no internal battery so only works while plugged in... it is NOT rechargeable.Tried contacting the seller but no response.I'd recommend buying elsewhere

Ideal for small and delicate jobs and projects

bits missing. Amazon stop selling these waste of money i could have made this and it would have been better. Shold be sold for £5 all it worth dnt buy people

Bought 2 to teach basic glass engraving,But will need to use power packs, They lied!
