My Q5 P1D gets almost daily use as it's my key-ring light. I have had it several years. I had to drill another lanyard hole as the first wore through and this second hole is almost worn through as there is metal to metal contact with the lanyard I use. I still have two more areas that are able to be drilled when this one fails!!
I also use as my primary work light a TK11 R2. This light gets chucked in my tool bag and quite abused and used again almost daily. Both lights have performed very well and if they do start playing up a quick strip, clean and lube up sorts them back to full working order.
