I bought this one after someone rear ended me at a stop light and bent my steel carrier. So to start, assembly, I read most of the reviews and that seemed to be the one that brought the ratings down. I am 60s years old, and disabled. I was able to but it fully together in about 30 minutes. Yes there are a lot of screws, but all I did was set it on a long folding table and sat in a chair to fully put it together, The directions are very poor, just basically a small picture with a diagram of how to put it together, would appreciate a better set to make assembly a bit easier. It is very well made, and sturdy, fits and holds my Victory 10 Mobility perfectly. I love the tie downs, my old one did not have any, I do wish it gave an options to place the tiedowns in a different location, but still love that it has tie downs. I also love the sides, my original steel carrier only had about a 1 inch side rail, I was always afraid that my scooter would fall off if my straps broke, this one has about a 7 inch side, all around. One of the factors to consider is how high it sits, depending on your vehicle. I have a F-250, non-four wheel drive, and when I installed it, it sat way too high to be able to roll my scooter up the ramp. So if you are going to use it for a mobility scooter carries like I did and have a high sitting vehicle, you will need to get about a 2 inch drop hitch to use, I just added that the other day and it now rolls up to the platform with no issues. The other great feature, is the weight, about 38-40 pounds, my original weighed about 85 pounds, and was very hard for me to move it to one of our other vehicles. Over-all a great purchase.
