These are not as good as i was hoping.. the sticky side is not very sticky and you only get one shot to get them on right. If they are not exactly right when you place them, they lift up and are quicker to come off.

This product misses just about every mark. It's not reusable, it doesn't stick, and it doesn't look good. It just doesn't work.Now I'm not new to adhesives, stickers, etc. I have managed to put on a 32 inch contact LCD screen protector with 0 particles/hairs, as well as 6 ft x 4 ft vinyl window stickers without bubbles. So it's fair to say that I know my films and stickers.First of all, the adhesive is just really bad. It is not the good kind you find on reusable products, which is usually silicone based. The adhesive used here is your standard type found on most tapes, which will rub off with friction. It catches every particle of dust and hair it can find, and can not be washed clean in water. This results in trapped hairs and particles behind the stickers, which also forms air bubbles.The plastic (vinyl?) is extremely thin and rigid. Trying to bend the stickers slightly to lift a corner, will permanently peel that corner up. Even using a piece of tape on the corner to peel them back just warps the entire sticker so that it is permanently bent, and won't ever lay flat again. Trying to gently push an air bubble out simply deforms the sticker. Finger nails easily leave marks that do not ever go away.The adhesive is rather weak, and the plastic has a memory. Because of this, by the time I had finished placing all of the stickers, more than 1/4 of them had already begun to lift up and from the keys. Almost all of the rest were beginning to peel up, as the adhesive slowly began to detach from every single sticker.If you were looking for high quality thick vinyl stickers with static cling or silicone backing, this is not that.

It does help tremendously.
