First off, let me say I'm not very mechanically inclined. Second, I tend to swear when I get frustrated and can't figure something out. You'll be happy to know I didn't swear during this assembly, so there is hope for you. Instructions could have been better, but I've seen a lot worse. Here are my notes and I've added several pictures to give you a better visual.Step 1- Laying out all the parts - Do this! It will make things easier. Don't have to pull out all the hardware to start. I didn't have too much trouble figuring that out. Manufacturer could have put a sticker on the hardware bags to make it easier.Step 2 - While this is pretty easy, I did run into a problem during Step 7 because the tubes wouldn't line up. Turns out, I had to unscrew and flip around one of the "A" tubes and the #10/#11 Long Hubs and then things lined up.Step 3 and 4 - These are the easiest steps. Please note that the #18 bolts came attached to the #8 Tubes. Just unscrew them and set aside. Then reuse to attach.Step 5 - Again, pretty easy. My directions said "See image 3a, 3b, 3c". Should have been 5a, 5b, 5c. Typo.Step 6 - Easy. Note that #17 bolt was threaded all the way - not halfway like the picture on page 1Step 7 - This is the hardest step. There are 3 "A" Tubes and 2 "B" Tubes. The "A" tubes go on both ends and the middle. The "B" tubes slide over them. You adjust the lengths and overlaps based on width of pool. I only lined up a couple of holes for A and B. The others, I had to drill a pilot hole. I used the #15 screw with a power drill.Step 8 - Not too difficult. Although note that the small slotted grooves in tubes A and B will NOT be lined up all the way across. I lined up all the "A" tube slots and then the slots in the "B" tubes were close to it and line up with each other. I tried to space out the 8 straps as evenly as possible. I used a pair of pliers when clamping the plastic connectors onto the solar cover as it was too hard to push through by hand.It took me about 1 1/2 - 2 hours total. And I did it right out by the end of the pool deck. I partially tried to roll up the cover, but it was getting a little off kilter on the non-wheel end, so I unrolled it and will try again later with another person helping to guide and keep straight the cover on that end. Note that you you need to loosed the #3 threaded knob when rolling up and tighten it to stop and adjust. I may also need to trim the solar cover a little bit. Pool is 16x32 and cover is slightly larger so it's a little bunched up in spots. Overall, I give it 4 stars - mainly for the moderate difficulty in assembly. We'll see how good it works. Hope you find these details helpful.This unit makes it so easy to handle your pool cover; however, the seams in the junctions rip the cover, so I would recommend covering those seams with either a duct tape or some sort of padding.Other than the sagging in the middle, we are quite pleasedWheel to wind it up broke after a month of useAssembly was not difficult. Drill pilot holes for the self tapping screws. Straps were good, but used different cover fasteners so as to not puncture cover. May need to put some weight against the legs to stop it creeping during winding. Really needs to be able to wind from either end, ( second wheel ) to keep the cover properly aligned during winding. Otherwise, works well, locking screw is very handy.Handle attachment was missing and CharaVector promptly shipped a replacement out. Thank you for your attentive customer service!So easy to assemble, we’ll made. Recommend 10/10.Update 07/15/2021: The seller reached out and said they were redesigning and would let me have one to test when it is done. Moving up a star to address their fast response and actually reaching out to me. If they address the design flaw in the new version I will update my rating to reflect the new design...Pros: This thing is great vs wadding it up on my pool deck every day, so easy the kids can use it.Cons: Keeps dropping sheet metal screws into my pool. I even tried locktite to hold them in. Not sure how to fix the issue? If the vendor has a way to fix would love to hear it? At this point I think it would take a new extruded aluminum core and then red locktight before it was fully assembled as the holes are now worn out and will no longer hold the screws. Probably would help to have more overlap in the extrusions as well. One more section to allow for .5M overlap vs the .25M now.If they can fix the issue with the screws dropping before it ruins my pool liner I will make it a 5 star. But at this point I am not sure how much longer it will be usable after only a few weeks.
