Edit: Poll now closed. See post #29 for analysis.
Given we lost data on the previous "H502 Wet Poll," and given that I received several criticisms (with which I agree!) for setting up the poll badly, I propose we start over here. The objective is to see if there is a systematic leakage problem with the new H502, or if there's not a systematic leakage problem with H502.
This poll will not be anonymous as the previous one was--your username is attached. The purpose of this is to help reduce the number of "drive-by shootings" the poll may (or may not) be receiving. We should be able to match your vote to a post with a description (and hopefully a photograph) in the thread.
You get to determine how you test your light, of course, but many people dip the light in a glass of water, or take it into the shower. (One brave soul sent his through the washing machine and dryer!) The H502 is rated IPX8, and according to ZL's website it should survive 2 meters depth for 30 minutes. PLEASE DESCRIBE YOUR TEST, whatever it may be.
PHOTOS are STRONGLY ENCOURAGED. (I wish I could require them!) Photos help us verify real owners and real cases. (Anyone can just say they own an H502 and that it does or doesn't leak.) Ideally we should be able to match your vote to a photo of either (a) the light during the test or (b) the light after the test, showing it either dry or wet inside. The poll's open for two weeks. We can do another later if we like.
Also it would be interesting if you could list any bias you may have either toward or against ZL. Wouldn't it be interesting if fans found no leaks and detractors found leaks.
Finally, to both "fans" and "haters" of ZL: Please don't fabricate data one way or the other. We're trying to get a valid measure here. Thanks!
