This thing is an incredible value. I'm not an expert with projector screen quality, but for someone who just wants a screen that has a remote and looks great to an average person, this fits the bill. The price is unbelievable, the screen works great, the remote works perfectly and after a few months of using it, I can say I truly love it.
A few things I did notice:
The control on the wire is pretty large and since I didn't ever use it, I actually used double-sided tape to hide it behind the screen housing along the top and then ran an extension wire down the right side of the screen. The wire originally comes down the left-side (if you're facing the screen).
Adjust the screen first using a small flat screwdriver so it comes down exactly as you want it to. You'll need someone there to help you otherwise this will take forever.
There is no mounting hardware included. I wish they'd sell this with it, but it's a small gripe.
The remote is an RF remote!! This does not work with a Logitech Harmony remote or other universal remotes which only deal with IR and Wifi signals. There is a way with some really difficult workarounds. I'm looking into one of them to implement in the summer, but for now, I have to press the button on the screen remote and then have the Harmony control everything else. That is a major disappointment, but I can't blame the screen for that. If this is crucial, look for a screen with an IR remote or you'll have to do a lot of work to get this working with a universal remote system.
UPDATE: I found a much simpler solution using a Tuya compatible RF/IR remote (it's like a small puck that can emulate an RF signal and listen for IR signals and Wifi commands through a smart platform.
Connecting this device to the smart things app and setting up a virtual button allowed my universal remote to press one button and control everything. One button now pulls down the projector screen, turns on the projector and the speaker and launches my Shield TV box. This setup also allows me to use my voice to control the projector screen via Google and remotely via the Tuya or Google Home app. There is a thread of Reddit that goes through step-by-step instructions on how to set this up but I'll try and find it and repost it here later.
100" isn't as big as I thought it was. Do some measuring before and be sure that's the size you want. I think I'd have gone all the way up to 150" had I realized that in advance.
