I love it! I gave 4 stars because I was expecting them to be a bit bigger, they are so tiny but I really like them, they work great!
Pros
Extremely thin and durable: only 0.027 inch (0.7 mm) thick, so it does not interfere with closing the laptop lid. It is attached with double-sided tape and can be removed if necessary. In addition, it resists wear and tear and remains firmly attached.
