I needed a tall door and not many to be found without paying custom. This door was fairly easy to assemble and does require planning when it comes to fitting the screen into the frame. I used painter's blue tape to hold the screen pinning it down in multiple areas before I began to insert the rubber beading securing the screen. The tools they provide are fine -- I found the slot tool got the bead into position and then the rounded tool worked best if I angled it as I ran it along the bead trough. Keep checking the screen is not being pulled away or shifted as you do this process around the periphery. Cut the excess and you are done. I wish the beading was on the inside of the screen instead of the outside. I had to drill some custom holes on the bottom because the door was too tight for my door fitting and would catch. When I modified the holes so it didn't push as hard on the screen door tracks it all worked fine and opened and closed well -- I like that the wheels are metal and not plastic and I think that will make this door work for a longer number of years without the wheels cracking and breaking which happened to our old door with nylon wheels.

It was relatively easy to assemble. It works as expected except that the rollers seem to slip no matter the screw setting.

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.

I'm very happy with this door but let me start off with the Cons:
1. Like others have experienced, a small part was not included in the sealed bag of screws and latch parts.
For me it was the latch part than goes on the wall. I don't need it but I notified the company anyway. They give their phone number and email address on the instruction sheet. I suggest you immediately compare the parts you receive to the pictured parts list of what should be there.
2. The 1.5" wide rubber seal/bug strip that runs down the length of the non-latch side of the door frame was curled up against the door frame member from being tightly packaged so it didn't quite reach the glass of the sliding door. No biggie, I laid it out flat on a work bench and blasted it with a heat gun and now it's fine.
That's it, no more Cons
The door assembled quickly and even putting the screen in was easy with two people - one to keep some mild tension on the screen to reduce "billowing" in the center.
The spring-loaded, expandable roller bars at top and bottom are very clever. This will make perfect sense when you do it. Install them but do not tighten them. Compress them both when you situate the door on the sliding door tracks and then let the springs re-expand them into position and you've got a perfect fit. Then tighten the screws to lock it it. These expandable roller bars are what give the door a 6 inch range of sliding door frames they will work with.
This is not a heavyweight door and it was only $90 so that's the context in which to evaluate it.

The product came very fast and I was able to install it myself. It fit perfectly in my door frame.
