I run an Exposure TraceR and the tab on the silicone ring ripped off the other day. Sent a query on Tuesday evening asking if they sold them. Got a response on Wednesday morning asking for pictures so they could Identify the correct replacement. Got home Thursday evening and there was a first class package for me with a replacement ring. The light is getting on for two and half years old I think, so outside warranty. Exceptional service, and excellent lights.
