I'm needing a solar cover reel, and I believe I am going to go with the FeherGuard. I can't decide between the 3 different models. One has a big wheel that sits in a base - Wheels Reel, another one has polyethelyne triangular ends - Blanket handler plus, and a third design has metal T ends - Knock Down, I believe. I bought a Horizon HV-10 last year, and it didn't work well for us at all. The bearings were cheap plastic, the tube sagged, and it took a ton of effort to roll up our cover. Our pool is an inground 20 x 40. Any input would be greatly appreciated. And it doesn't have to be FeherGuard, either. I just want to get it right this time!
