I have been in Mauritius now for about 3 months and have been using the Tovatec regularly for all my night dives. I will say, its an excellent product, using the sanyo rechargeable eneloop batteries. The only weakness is the lack of an optional narrow beam and the magnetic on and off swith which can accidentally go on when packed with a bunch of gear as it happened to me, otherwise, well done Tovatec.
