Worth it if all you want to do is trim your dog’s nails??
Better ask your dog about that. Ours doesn’t like the sound of the Dysan vacuum cleaner, much less the gardening leaf blowers and grass whips.
I bought this the last time it was on Woot. The motor burnt out when I was using a cutting tool to score 1/8" particle board. Score, not cut. 1/8" thick particle board. The motor in this thing is a joke. When it comes to tools, generally you get what you pay for. Another thing to consider is that Dremel attachments don’t fit, and that’s pretty much all there is out there in terms of rotary tool attachments.
I bought one of these last time on Woot and have had no problems with the motor and I just put a Dremel branded cutter on it with no problems. It fits fine.
