Warning: I'm a noob level door installer and this is the first (and hopefully last) ever door install.
Negatives:
If you're installing this on drywall/studs, you will need a headboard. It doesn't come with one. If you don't know what that is, me too. It's pretty much a board that needs to be at least as long as the railing between 4-6" wide and 1" thick which you'll probably want to paint it. This is to support the weight of the door. You'll need to buy the board and some 3"-4" screws (probably black structural ones) to screw the board into your studs. There are mentions of this in the instructions but not in much detail and I didn't notice any in the description on the site, which would have been good but probably would have not bought it.
The second big negative is the railing holes are spaced so you can't screw them into the studs. You can get one, but the others are relying on the headboard to support the weight of the door. This may affect your ability to center the railing so get a decent headboard. I believe my studs are 16" apart for reference.
Minor negatives include the lack of predrilled holes that guide you for the hinges. I had to do a lot of research to figure out how close together to place the door to screw the hinges in. FYI, you want it around 1/4" or less and make sure the doors are lined up.
I didn't like the pull handle that comes with the door (yes it comes with it) so I'll install something else but I 3d printed a temporary one in the mean time to avoid putting holes in the door.
You will have to drill into the floor to secure the fixed side. I highly recommend getting some painters tape and letting the door hang where it needs to be and outline where the piece needs to be with the tape. Gravity for the win.
Positives:
I think it's a beautiful door. Hardware feels heavy and very nice quality. The doors itself feel high quality. Its solid wood and the weight of all pieces (doors and hardware) are heavy which adds to the feel of quality. This is a great option for somewhat awkward size openings and limited opening spaces. I had a very difficult time finding a contractor that would recommend and install a single door for me and was ghosted by all them after seeing the opening.
This is a great option even for a first time noob installer. If you're going to go for it and have limited experience, it's not impossible and the fact that I was able to do it with good results means you can too! But, take your time and think things through. I gave it 5 stars because it really is a good value for what you receive.
