320 replacement
I had the old 320 on my pool, which is about 15 years old. Screwed on easily with no issues. Came with all the hoses and everything you need.

Doesn't impeded flow as much as other brands.
I haven't installed this yet but I did a lot of research before buying this unit. Because of the design the flow is not affected as much as other brands circulating more water and easier on my pump.

Comically bad design
I have one of these. Take a good look at the design. How is water supposed to travel through there? The answer is that it doesn’t. I put a flow gauge on mine and it BARELY moves. There’s no possibly way for water to flow through with this design. The intake has to be moved away from underneath the thing *HEADSLAP* then it actually works extremely well.
