I use the BT-FP2. It is a somewhat robust and heavy duty model. The pedals are quiet and they feel steady and clear during operation.
The possibilities are adequate for my use, that is, scroll left and pageturn right. But you can of course set that to your own preference
There's no problem with the virtual keyboard, after the tweak as described by Mike that is.
I think it's well worth the € 49 I've paid for it.
I forgot to mention that it is BT 3.0 +
