The set comes with three covers. Two out of which are very nicely built and works great. There seems to be a design flaw with one in the middle. The cover does not slides smoothly and I broke it when tried to apply little force. In general the deal is too good. I have ordered 10 more sets to share with colleagues and friends. Highly recommended.

Nice professional package. The covers look like brushed black aluminium so on black frames it would be elegant. Also adhesive is already on. For that price is obligatory to buy!
