High quality shows (7 years in storage)
I stopped playing in 2009, and yesterday I started going over my markers to see in what sorry state they were. My DM5 ad been cleaned and stored with no air nor battery. It started leaking and the On/Off wasn't working. I disassembled the whole things. The two urethane o-rings were in pieces. The On/Off 009-90 and the LPR seat o-ring (006). Replaced both with buma, cleaned grease and re-apply, and my DM5 is working perfectly.
The excellent documentation, parts kits and excellent design shows. Congratulations to Dye to achieve the sort of time resilience on an electronic marker only comparable to simple mechanical like CCI Phantom.
