Last year we had one laser stop working and found out that there is no rebuild capability other than battery replacement in the US. We ended up getting in touch with the manufacturer in Australia and they swapped out our old set for a new set for the cost of shipping (not cheap) and some dollar amount that was cheaper than a new set but still pretty expensive.
I was pretty disappointed that my set only lasted about 18 months and for over $300 new you’d figure sniper would use a more reliable laser. Once you invest in their system (which is a great tool) you’re pretty much over a barrel when they fail since there is no rebuilding them and little support other than warranty collection here in the states. You either toss them and use whatever else is out there or you keep paying. Hopefully this set will last more than 18 months.
