Not so good
"Unfortunately it didn’t work out so well for me. The new on/off switch was suppose to “easily” slide between the two screws in the handle but it didn’t fit. I ended up pulling the yellow wire out of its slot so the next day I had to order another new one. The same day I ordered a battery Velcro strap and was charged two separate shipping charges. I had to modify the on/off switch in order to get it through the handle."
