I bought this product recently and am very happy with it. For the price you don't get one but two blackout blinds which is a bonus as our toddler's room has 2 windows and we found the price of 2 separate blinds too much. The sticky hooks provided with it are very easy to use, I found they were sticking on glass much better than on the PVC. 8 plastic sticky suction types of hooks are included and I find 4 per window on each corner work perfect. During the day we leave the hooks on the windows as they are hardly noticeable being see-through so at night we just have to pop the eyelets on it. They don't mark the glass when off either. The blind isn't falling off during the night but once every 3 days I would press the hooks against the window again so they stick well, no fuss. The fabric is really thick and blacks all outside light out. The edges are not too tight so let the light go through but we have a pair of thick curtains on each window and it is more than enough to keep our toddler asleep all night from bright evening to bright morning. Up until now we used a competitive brand which was also a travel blackout blind using many suction cups already sewn to the fabric but we find this one is much easier to use (altough only for windows fitting the size as it doesn't extend beyond 100x120cms). But it's perfect for us and I am very happy for the price I paid.
