To my happy surprise, I just received a box from UPS with a brand new Sunpak G-flash inside to replace my flooded one. I have certainly had issues with the Sunpak, as the first one quit after 3 dives for no apparent reason, and the second one flooded regardless of my care and careful handling. I have to say, however, that ToCAD America has come through with flying colors in standing behind their product. I simply sent them the strobe, with a copy of the invoice and a note explaining that I had carefully serviced it, lubed the o-ring and properly installed the battery cover but it had flooded halfway through the dive. I drained the seawater/battery acid out and sent it to them as it was pulled from the water and asked if they could find a reason for flooding, as I couldn't. Three weeks later, new strobe. Now, if they would just redesign that silly battery cover so it isn't so sensitive.
