Query: Broke on its own after a couple of months

I have owned two within a year. The first one broke after I dropped it in the sink. As for the second one, after reading these reviews, I thought I had it nailed down that this was the one to buy. Not sure if I bought a lemon, but this stopped working after a couple of months (not sure why).Now I am looking into another one, but I am skepticle that these niche trimmers are as durable as any standard electric shaver.Somebody prove me wrong.
