Exactly what I needed to get my pool going this year. Ionizer are so awesome. Less chemicals needed all summer.

This item is needed every year. It keeps the green Out of the pool

The copper ionizer fit our Power Ionizer model 454007 and is working great so far. The original last a little over a year so hoping this one will also.It was very easy to install.Before I ordered, I asked if it fit my model but no one seemed to know. The seller replied it fits all "Main Access" power ionizers. Well, I don't see "Main Access" anywhere on our manuals. Finally, in teeny tiny print on the bottom, back page of one tiny tag, there it is: "Main Access". Everywhere else, it is described as "Power Ionizer". Other than this initial frustration of just trying to figure out if I was ordering the right part or not, everything else was great.We are fans of copper ionizers to assist in sanitizing our pool and will most likely order another one from this company. Thank you.

Prompt shipping, item as described.
