The fine print says not to expose to sunlight or water. Unfortunately I bought it to repair a bird feeder so it will get both. So it probably wont last for years, but if it gets a couple of seasons it will be worth the price.

So far I havent any dislikes. I use the pens on a sheet of Polycarbonate plastic. I place the plastic sheet over a crochet pattern which I use sticky dots to hold the pattern onto the plastic sheet, I then use the markers to mark the spot on the plastic where I left off on the pattern. No problem to pick up where I left off on my project and it keeps my paper pattern clean and neat.

This has been a life saver for me at my school this year being able to put a small hole and tie rope around to make personal bubbles

This is nothing like plexiglass. This stuff is tough. I cut it on the bandsaw. Drilled it on a drill press and sanded it by hand. It cuts and drills easy but I was expecting the same as I get with plexiglass, which are fractures or cracks wherever youre cutting or drilling. I made a very narrow piece, and after cutting, drilling, sanding, and polishing, it had zero cracks and I stopped being gentle with it. It will scratch as its plastic, but scratches can be sanded and polished out.

This is totally fine and is probably supposed to be like it is. It came with protective coating you peel off. However, I was looking for something bendable. It does say bendable but it only slightly bends. I needed something that actually bends in half.

We were lucky, the size is absolutely perfect for our need, the thickness is certainly going to keep our dogs from running through it (they had created their own doggy door though our screen), and unless you are looking closely it is not noticeable (almost perfectly clear). I used some quake wax to hold it against the frame, anything sticky should work as well.

I used it to replace the broken glass on an analog meter that goes on a Collins KWM-2 Ham Radio Transceiver

Used this to drill 350 holes in and make a multi mini capacitor for our front yard Tesla coil Halloween yard decoration. Not expensive and it holds up to the abuse of taking it down and putting it back up over and over. No complaints here.
