Review on UBOTIE 84Keys Colorful Wireless Computer Keyboard And Mice Combos by Lawrence Allison

Although this keyboard is cute and makes nice noise when typing, I am annoyed by the fact that I cannot use some functions. I can't use the speaker function (e.g. turn it up or down), I can't switch tabs (F3 key on other keyboards or computers), I can't use the keys on the right (Del, Home , PgUp, PgDn, end) and I can't copy and paste either, it just doesn't work. I'm not sure if this just happened to me, but I wasn't very lucky. The reason I give it 3 stars is because the mouse that came with it gave it a higher rating. Without it I would give it a 2. (I also connected it to my iMac desktop, so maybe that's the problem?)
