I have struggled with Bugsy's nails forever due to their size and hardness and quick growth. I have used a rechargeable dremel for years to do his nails with the battery usually loosing its charge before the job was done and the whole process took FOREVER!
I was hesitant to use the corded version for fear it would run too hot or be hard to work with - well was I ever wrong!
A VERY kind soul sent me a wired dremel and I spent a few nights getting him used to it - first just touching it, then touching it when it was plugged in, then touching it to his nails, then touching it when it was running and then finally using it on his nails.
Well several things have happened.
#1 I can actually do all his nails without running out of juice and it is much faster
#2 he clearly is more comfortable with this dremel on a high speed than he ever was with the cordless version - so more speed is better (in our case)
#3 his nails are getting shorter - this has been a constant battle for me. I want them shorter but even doing them every other day I wasn't getting anywhere. now I am doing them twice a week and getting somewhere
So if you aren't have a great time with your battery operated dremel may be its time to try the corded type
And a big thank you to my angel
