Quality salt cell

In my experience they seem to last longer if you clean them quarterly. I use vinegar instead of the harsh muriatic acid. It takes longer but is easier on the metel.

Good

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.

I recently had to replace the cell with a new RJ45 classic cell. It was a seamless process installing the new one
