Perfect replacement
The new cell was an exact replacement for my original one that had stopped working. Installation took 10 minutes! Purchase and shipping was excellent!

Not Effective for Pool Size
I have a 20K gallon pool. Initially I had a CPX36 rated for a 40K gallon pool. When I replaced with the CPX16 which is rated for 20K gallons it cannot produce enough chlorine to keep the algae at bay. My pool has turned green and now I must treat with chlorine. If you buy CompuPool but double the capacity of your pool if you want it to be effective.
