Do not be surprised, the door came in a Corrugated Tube not a flat box like I thought it would. You will need an extra hand to assemble, but once assembled it was easy to install. The door rolls smoothly on the track and latches tightly into place. Definitely worth the money and will last for many years to come.

The item works great, was easy to install, and seems to be sturdy. The only drawback was that the screen material tears easily. I had to get more sturdy material at Home Depot.

I've replaced a few screen doors with what the big box stores had available and they have been very disappointing. Lightweight frames and cheap plastic rollers. This door frame is considerably more heavy duty and has metal wheels top and bottom. The door glides MUCH better and I have confidence that the frame will last longer because of how it's built. It was shipped in a large heavy duty cardboard tube and the assembly was very simple. I'd suggest you watch a youtube video on how to rescreen a sliding screen door to get some pointers if you haven't done it before. This door is a far superior choice to what I can get at the big box stores for the same price

Putting this together I was surprised that the four sides didn't interlock. It's held together by 8 sheet metal screws. It seems to work well though, the screen was a pain to put on. I found it easier to put it on while the door was already up on the frame. A decent buy

After a rough start with the rail for the larger frame door sent with the kit, the seller replaced the part without issue. Building the door is not difficult, but I strongly suggest using a large table to put the kit together because otherwise, it involves a lot of crawling around on the floor and bending over to work. The door is sturdy and glides smoothly on the aluminum replacement runner I installed in place of the decades old vinyl runner that was slowly disintegrating and helped destroy the old screen door. Take the maximum and minimum sizes listed to heart. The doors will absolutely not fit in a larger or smaller opening. I knew this door was going to be a tight fit as we have an odd sized patio door frame. This IS NOT the fault of the seller and I fully expected to have to perform surgery to make it fit. In my case, the door required cutting 3/4 of an inch off the height of the door. This can be done, but since the kit isn't really designed for it, necessitates a fair amount of mechanical ability requiring exact measurement for cutting of the steel vertical frame and drilling of new holes for the hardware and you only have ONE chance to do it right.

Overall, the door is a good product. Very sturdy and smooth rolling. Installing the screen itself isn't difficult. The entire process simply requires the right tools, time and patience. The door is substantially more rugged than the old door with its cheap and thin aluminum frame, which is exactly why I purchased it.
