Review: Very very happy - Pleasantly surprised to find this on desertcart. Works great and quick delivery. Price is well worth it.
Review: Installed and Working Fine (See review notes) - I used this to repair our old Jacuzzi tub that came with our house. A couple notes: 1) It doesn't come with a tube lock nut like the original pump equipment, but it doesn' actually need it. 2) The hole on the housing that the treaded side gets push though is set up for the original equipment that had 2 flat sides. So I drilled out the plastic cover a little bit so this new switch would fit through. I guess you could use a file or similar to make to flat sides ont he switch, but seemed like making the cover hole round was a better idea.
