Pros: automatic, pump timer built in, works well
Cons: display codes not explained in manual
the kit arrived sooner than expected, relatively simple to install, If you can place generator close to the jet it turns out you don't need the flow switch, but I installed it anyway. The unit will not generate if the water is too cold, it was also too cold to swim. I think this thing saved me about $200 in chlorine tabs and shock last season alone. No more red eye
