Some of the earlier Fenix lights had problems - I bought quite a few L2T lights and have had a 60% failure rate (3 out of 5). The L2T were a problematic light - so this isn't indicative of all Fenix lights - just this model.

Plus 1 dead E01 (out of 4), but, the E01 was probably killed from reverse polarity (not by me...).

And I own a P1D. My P1D has lasted several years of good use problem free.

Their later lights don't have the same problems as the L2T and from most reports are rock solid. I still recommend Fenix to others.
