Coast led lenser frogman black 7457

The version I bought is the older twist type, I have seen reviews of the newer that then complain about the switch rusting. But of course a twist that serves as both on/off and entry to the battery housing has a possible fatal disadvantage. However the funny thing is that it is TüV certified to 60m, so let's see what time brings.I have however replaced the o-ring and put more silicon lube also up the screw.As for light this is more than adequate for a back-up torch, and I guess with regular servicing & the fact I never go below 40m, I don't really see an issue.Delivery was prompt, so no issue there & for the price I am not disappointed.
