I just got this light from Massdrop. It is a great light, but unfortunately my tail switch seems to be wonky. It is very unreliable. Sometimes it works, sometimes it does not. When I do get it to turn on, changing modes is a little crazy since a partial push might change modes or the light might just go out. I took it apart and sprayed electronics contact cleaner into the switch which seemed to help, but not completely alleviate the problem. Where can I get a replacement tail switch? (Massdrop does not have any extras to swap me a unit, they will only give me a refund.)To be fair, ReyLight basically is a "modder", except he does it in volume using factory production instead of by hand. He's just one guy who uses the community to help design his lights and then uses a Chinese factory for production. The result is usually very very good, because its basically an enthusiasts' light built using some of the latest innovations and ideas from the hobbyist community, but then produced at a China-price. And the results usually speak for themselves. ReyLights tend to be awesome and very fairly priced.
Thanks for any help!
