My pool was swimmable (I don't say "done" since there's always something needing work ;-) back in 2005 and I've been through 3 T-Cells since. Got an Aqua Logic PS-8 w/ T-15. Crapped out again end of last summer and installed a Generic this year. Had a little doubt but it's been going strong since May install...seems to actually produce the same chlorine at lower settings even. At $350 I thought I'd pass on my experience. If this topic has been previously covered...my apologies.

Anyway, Happy Swimming...Ralph
