The screen seemed bigger that I had imagined it would be for some reason, but it just fits crossways in the back of my car. The plasticy smell goes away after a couple of weeks. The screen itself unrolls from the base using a single finger and retracts with a similar amount of force, the whole mechanism is nicely balanced. The reflective screen itself is at the top of a longer roll of material, so that you can use it on a table top or standing on the floor. I like the fact that the whole thing is one single component with no extras to carry around.
Only downsides are that it's a bit heavy to carry any distance (e.g. on the train) and the catches could be a little stronger, but altogether great value for money.
