I bought this as a replacement cell. Have for 3 weeks approx and seems to be doing a good job. Old celldid not last as long as it should have, but there was 40% warranty remaining plus a discount which really helped take the pain away. The warranty was suggested by all representatives which was a pleasant releif from the scratching and clawing required by other companies to substantiate a claim. Kudos for that.

When the system works correctly it is almost maintenance free for weeks at a time vs, daily with the chlorine system.

Hopefully another 5 years
First installed the system in 2011, after getting the Water Fault light I learned that the cell need to be replaced. It didn't last as long as I hoped but I swim year round in AZ so that's probably not that bad.
