So, I returned the strobe to the local Japanese dive shop, explained to them, the best I could (sign motions etc) what happened. They sent the strobe back to INON.
Meanwhile, I bought another INON from a different dive shop (previous dive shop had no stock). 1st dive with the new INON strobe, halfway through the dive, quit working. I was completely ticked. Two in a row..... I knew I did not over tighten this one. That same evening I took it back to the shop where I bought it, demonstrated that it would not work. They sent it to INON. Two weeeks later strobe one and strobe two are returned from INON to the dive shops. Strobe one definitley flooded, but they fixed it....no charge! Strobe #2, best I could tell from talking to the dive shop, did not flood, but shorted out...... but was fixed.....no charge! INON customer service is great!! I now have two working strobes. I have yet to dive with either one, but plan to this weekend. Hopefully my strobe woes are over!
