OK, so I have had 2 of these. The first one failed, flooded, and was unsalvageable in its second year. The second one also flooded during the second year. The sealant used in both failed. So I disassembled it to see if it could be repaired. I lucked out and was able to salvage the electronics (Bag O Rice). I also noticed that the manufacturer used the low mAh batteries, so I replaced them with stronger batteries, 2300 mAh. I resealed the globe with a Marine sealant which has lasted for three years. Now there is NO sealant out there that can remain in the presence of chlorine in water forever. The sealant I used is now softening and will need to be cleaned and resealed. I will do that repair during the winter. However, if I were to purchase a third, I would likely tear it down and rebuild it as I did the last one before I use it.

The clorinator will find a way to the edge of the pool where it will reside until you fill it with new tablets next time. Then, within minutes, it'll be up against the side again. There's no reason for it to stay in the center of the pool where it might be pretty.
THEN, it fills with water. Yes, within 2 months, the clorinator was filling with water and the pretty light didn't work any more.
This, for me, was a total waste. I'm back to the simple clorinator.

Only worked for 2 months until what seems to me the silicone sealant allowed water to leak inside and ruined the batteries.
