Being in the USPSA circle, i am around more people than most with dots.
-A buddy had a Leupold delta point pro fail straight out of the box. Dot shut off on the first stage and wouldn't come back on.
My boss has had a vortex venom crack the housing and the glass came loose around 5k rounds.
My boss had another venom fail around 18k rounds. Shut off and wouldn't come back on.
Another shooting buddy had an SRO fail at 12k rounds and another fail around 2k rounds.
I've been lucky, I've had nothing but good luck with my DPP, Romeo 1 pro, 507c and Venoms.
Been shooting any matches lately? I've just done some steel challenges.
As for optics, I don't expect anything to hold up to months of being beat, dropped, racked off hard surfaces, stored in humidity, bad battery, etc. Not saying that's what they did but to say an optic failed is to put blame on the optic when it could very well have been the Owner. For 2 people to have 2 of the same optic fail is quite unlikely.
Did those companies replace them free of charge?
