Good price and quick service.
perfect fit,does an excellent job of cleaning and spa depot 's price and shipping are the best
Spa installers put a solid top in but this one with the hole on top is working much better. The installers didn't care they dump a bunch of chemicals in water turned pure green and cloudy, we had to drain it and fill it again with the proper amount of chemicals as directed on the bottles. The water is crystal clear and tested accurately, don't trust installer if he's having a bad day you get the wrong filter and wrong amount of chemicals.
The description was accurate and the filter came fast and fit. Price was pretty good too.
They were delivered quickly and to my front door.
Perfect fit for my spa. Great price, with fast shipping
Filter went in easily! Working great.
perfect size and works great
The web site showed enough information to be able to order the correct filter. The local spa company said to order on line for the best price. Shipping was slow but it was free. I will use spa depot for future spa purchases.
