Let customers speak for us
from 640 reviewsHelped me get my light installed correctly after liner change
This machine cleans 10 times better than my previous one and is worth the cost. However, I’ve only had it for 2 weeks. The last one lasted about 6 months and never cleaned well even though it had 4 stars when I bought it. I hope this new one remains strong for a few years
Fast service
The pump was a great value and it was described perfectly. The product was shipped fairly quickly and it was well-protected
After much research the value of the product is good. It was shipped fairly quick and it arrive in a well-protected package.
Very happy with this purchase fits and work as described fast shipping
Loved how fast it got here. It has small wiring and I was glad it was in a protective envelope and it arrived without breaking.
just as listed. well packeged, fast ahip, works fine. purchased to remedy issue with heater and ozone injectorboth operating together. might have been able to just bend old switch a bit but did not try that.
Great customer service and knowledge of product. Asked of compatibility and they had the answer. My intouch2 was not working so I researched new intouch3 from Spa Dealer and they wanted $75 just to come out, then $125 for up to an hr...just to confirm what I already knew. Contacted PST and they had the product and confirmed compatibility. Saved me some $$.Thanks PST.
pool definitely running much better with all the updated parts
This was a perfect fit for my aquarite salt system. And 1/3 of the price of anyone around
