  1. Save money with this product 5 Star Review

    Posted by on 11th May 2022

    All owners of ozone equipment understand they eventually wear out. Instead of paying for a new system replacing the modules is very easy and costs less than purchasing a new system. Great service at this location.

  2. bad from stock 1 Star Review

    Posted by on 28th Feb 2022

    This kit was bad from stock. I have used one before and it worked fine,not this one.What concerns me is I'm having trouble getting a replacement,no ones answering e-mails or phones.

    Thank you for your honest review. Sometimes there is a bad module that gets missed at the factory. Luckily, they are (DEL Ozone/CMP) replacing it! Wishing you a happy hot tubbing experience!

  3. As advertised 5 Star Review

    Posted by on 10th Sep 2021

    Excellent service by LYHT. As advertised, products were shipped and delivered as advertised.

  4. Renewal is better than new 5 Star Review

    Posted by on 23rd Aug 2021

    It is great to be able to get the renewal kit at half the cost of replacing the whole ozone unit - it takes just a few minutes and a screwdriver to swap out the ozone generator, and then its as good as new!
    (And Jen @ Loveyourhottub has been consistently wonderful over the years, Thank you!)
