Query: good little beacon

I purchased this beacon in a three light set. To date, it has been on three dives and doing fine. For the flooded compartment review, I recommend using a silicone lube to grease the O ring and threads. It makes it easier to turn and water tight (I use silicone lube available from Ikelite with all my flashlights). Also, check the batteries, mine arrived DOA and had to be replaced. My beacon is specific to which direction the light module goes in and will not work if reversed! The flashing red beacon stands out and isn't a throw away light like the chem lights (two thumbs up for eco friendly!). Hope this helps, happy diving my friends.
