Bests & Worsts Reviews from Amazon

I purchased this small clipper Oct 22, 2014. I use it to trim my beard once or twice a week. VOILA! First week of March 2015 the damn thing's head falls off. So let's see how many uses I got out of this. 18...maybe 19 weeks or just shy of 5 months. We'll say 5 months or an even 20 weeks. We'll say I averaged 2 uses per week. So I got to use this thing 40x and then FAIL. I'd like to think that a trimmer like this should have hundreds if not 1000's of sessions. I read the instructions and followed all the proper maintenance and care guidelines. Won't buy another one of these.
