I've been using Brilliance brand for the last couple months...I like it fine, it's in the floater with the plastic mesh screen over the open end, it keeps my water clear (I had issues with cloudy water when I used dichlor...my schedule is too screwy to keep up consistently), but no problems with that since the switch. I HAVE found, however, that if the level of bromine gets too high, it makes my hands itch a bit. Anyone that says it can be tough to dial in the floater correctly is right, IMHO. Especially if you use the tub a bunch for awhile, then get busy elsewhere with the floater dialed too high.
In any case....I switched because of general curiosity...to see if bromine would fit our lifestyle better, and so far, it has. Switch if you'd like, feel free to ask questions, and best of luck!
