I did get the Aqua Rite. I have a t-9 cell with mine, and so far, it has been more than adequate. In fact, I can turn it up only to about 35% or it produces more chlorine than the sun is burning. The folks here said get one with 2x the capacity of your pool, which meant I should have a t-15. Again, mine is fine so far, but I may wish I had a bigger salt cell in the heat of the summer. If so, I will replace it with a t-15 when the cell wears out.
