Pool coverThis worked great for my purpose.I have to state right up front that the pool for which this was purchased is only 7 feet wide. I bought a used reel which had a minor cosmetic flaw that was of no consequence. Because both ends had handles, I had to saw off the handle on one end to fit in the tight space I had available. Given that it was used and quite inexpensive, this was painless for me.I think this is quite sturdy in my application and it has simplified my previous manual process of placing and removing the cover from my pool. If you have a larger pool (longer span), you will want to get a sturdy pole, which I believe they sell. I was able to use a wooden dowel a little over 1" in diameter, but that was something I already had in my possession. There is a plastic bearing on each end. I can't say for certain if it's durable under a lot of weight. There are some retracting rollers on the bottoms, but I can't say if they're of any use to anyone else. My installation is permanently placed, but since it's so small, I can pick up the whole thing and carry it elsewhere if needed. This is dictated by the size of my pool, not the system.For Amazon, this is terrible and false advertising. The entire item and description indicates "all you need except the blanket". I received it and it is the end cranks only. The tube costs another $200 bringing total price to almost $400. This is more than heavy duty highest rated systems. Not what I expect or have ever received from Amazon. Rip offEven the people answering the questions didn't know.Had no idea and nowhere does it say. Every other reel kit I've ever purchased cones with the tube.I purchased this item about two years ago and have regretted it ever since. Today I'm shopping for a replacement since this item has been such a battle. Note the triangle shaped handles that (Do Not Spin!!!) if you real anything the handle should spin! I.e. You have to let it roll in your hand while trying to roll up your heavy cover. My wife refuses to do this now since it hurts her hands. Secondly the bar that the cover winds up on is made of several pieces that slide together and are then bolted together ( not too bad to assemble) BUT when you roll up the wet/ heavy cover it bowes which doubles the effort that it takes to wind and unwind your cover. And that makes it near impossible for one person to unroll the cover. And it slides all over, into the pool even! Frustrating! No offence to whom ever engineered this but it's poorly designed. Spend your money wisely.It took over 3 months of email and negotiations to get the correct product for my pool.They sent me 1/2 of what I needed and the young girl answering the phones was the worst ever.I could not get them to understand my problem.I finally got what I needed and the winder works pretty good.This product is exactly as advertised. I purchased this to utilize the previous solar rail pole that was 25 years old. The old wheel system just collapsed over time and I needed a replacement. Definitely saved money instead of buying a whole new reel system.The pole slides on the plastic casters perfectly, it must be a univeral configuration. I did have to customize the pole a bit due to removal of older wheels but that had nothing to do with this product. The unit comes with proper screws to double secure nothing slips over time. You will need a drill but the screws are self tapping. Project was easier due to having two of us put it together. Pruduct is 100% PVC, heavy duty, well designed and durable.Be prepared to buy new strapping because the original strapping is of pore quality and doesn't last long.Took forever to adapt it to existing axle from same manufacturer, which I had to use because the axle recommended for this model was not available on Amazon or through the manufacturer's site. Less sturdy than their previous model. Very awkward to roll as advertised. Easier just to slide it. Solstice seems to have a monopoly on such equipment, as least on Amazon. Many monopolies abuse their market power. I had bought a second set. Returned it for a refund, readily granted.The product was correctly described and arrived on time.The package had been damaged in transit with the aluminium tube distorted and plastic end of reel cracked.I got the aluminium tubes to connect and requested a replacement for the damaged end cap - no spare parts only return for a refund.The handle was one package and the reel the other so it would involve disassembling the roller, re-packaging it and returning two packages and I would be left with nothing.I assembled the two units and will repair the end with fibre glass if it catches the solar cover.The ends of the packages require proper ‘buffer material’ to prevent damage.I was under the impression that it came complete there was no pole to roll up heat blanket. Over priced for what you getWell made sturdy product, that I'm sure will last over 20 years like my old set did. The retractable rollers on the bottom are a nice touch too.
