The ozone generator works. But when you look through the translucent case you can see that it's almost twice as large as it needs to be. The case has a lot of empty space. This larger size means this ozone generator cannot be located in good location inside my spa. Had the case been made closer to the size needed to enclose the working bits it probably would fit.

It took me a while to diagnose that my cloudy water was due to a dead Ozonator. I was extremely frustrated trying to maintain my tub for a couple of weeks before I realized the cause. I ordered a new unit from Spa Depot and, as I have come to expect from them, it arrived the next day. It took only minutes to install and the effect was transformative. It’s now three weeks later and my water is crystal clear! I can’t recommend Spa Depot highly enough! They rock!

Perfect for my smaller spa (and probably larger ones too) and more affordable than most. Drastically reduced my use of chemicals to almost nothing (despite the disclaimers, etc)

This is the second one way valve that has failed after only 2 months, drains the hot tub down to the level of the jet where the ozone is injected and fills the ozinator with water. I ordered new teflon one way valve from a seperate source and hopefully the ozinator is not damaged. Works great when it works, but getting tierd of buying new ozinators when the one way valve goes bad and allows flow in both directions. Surely I am not the only one having this problem...

Easy install as a replacement part. Super fast shipping and good customer service. Would do business again for sure.
