I purchased my multigroom about six months ago, for the first 3-4 of months I thought that this was the best groomer I had ever purchased, in fact, I liked it so much I purchased two more for my sons. I use my groomer every day for no more than 3-4 minutes. After about 4 months of use the attachments were not securing well to the handle, over the next month or two the attachments fit so loosely on the handle that upon turning on the groomer the attachment will vibrate itself off the handle. I've been using the groomer but I have to firmly plant my thumb against the attachment so that it functions and to keep it from falling off the handle. My sons are having the same problem, I'm shopping for a new groomer, it won't be Norelco.
