Bought this keyboard as it is well reviewed, and as it is advertised as "compatible with IOS [and] Android". Indeed, the keyboard has some things going for it: solid build quality, and it connects and maintains a connection very well (additionally, I like that it is USB rechargeable, as opposed to apple's bluetooth keyboard, which requires AA batteries).
The F-ROW HOTKEYS ON THIS KEYBOARD, however, DO NOT WORK WITH MAC PRODUCTS (even though the user manual indicates that they SHOULD). Additionally, there are some quick-key shortcomings with android. I use a 2011 Macbook Pro, an iPad 3, and an HTC Evo Android phone. Have connected with each of these devices (and connected to my wife's iPhone 3gs), and the keyboard's hotkeys are non-functional with each of these.
Emailed Perixx customer support (well, not customer support, per se, but the only email address I could find on their website), and didn't hear back (3 days since email).
In sum, if you don't need or want: F-row functionality on the keyboard when interfacing with Mac or Android, or responsive/accessible customer support, then these keyboard seems like a solid buy. I can't comment on how it would interface with windows products.
I'll be returning this.
