Let customers speak for us
I ordered the wrong part. Customer service was very helpful. I returned it and within the week my credit card was credited back. Excellent customer service policy.
There was a delay in shipping due to postal service. They sent another part right away.
New model 59303 works great, but too bad the last generation Balboa WiFi module 50350 became un-useable.
Exactly as advertised and super fast shipping and delivery
Perfect
Took me almost 2 years to track this thing down, I’m very pleased with PST thank you!
Fits perfectly in my Dolphin Proteus DX4.
Holes lined up correctly, sealed our niche perfectly. Easy to install.
Easy to install, holes aligned perfectly. Seals great
Easy drop in replacement! Back running again.
Installation was easy and its very useful
