I have been using a Fenix L1D Light for over a year.
I have the Premium Q5 (superbright)model.
I also have a 2 AA body and a 1 cell cr123 body.
The light is very very well made and an excellent value.
Ive had no problems since I got it,and I do use it just
about every day.
NFI in the company,just a happy customer.
