Pros: Multiple BT pairings, switchable via keys... Excellent feature! I have my PC, Phone and iPad paired. When I get a text I need to respond to, 1 button click I'm entering text on my phone, then click I'm back to the PC. So, so convenient. I have a convertible stand-up desk the negative pitch option is nice Very comfortable

Overall Review: I am a systems infrastructure and web developer. I spend a lot of time on my keyboard. I'm not writing novels but I am typing a lot. I do agree with the another reviewer that the size and positioning of the keys are slightly different than a standard keyboard and takes some getting used to. I switched to this from a MS Surface because, after weeks, I was still slightly off hitting the backslash key above the enter on the Surface keyboard. Its smaller on the Surface keyboard and I use that key A LOT. The key I'm missing the most now is the semi colon. That'll take some getting used to as well. Decent build quality, as it should be for this price. Overall, with the right keys for me in a better position and bigger, AND the multiple BT pairings...I'm very happy with it.

Pros: Cheap

Cons: Spotty connection both for keyboard and very choppy audio playback on BT headphones. Both keyboard and headphones were within 4 feet of transceiver.

Overall Review: You may be able to use this where responsiveness is not important...like connections to temp sensors. Otherwise useless

Pros: Good build quality. Feels solid. Quick switching.

Cons: Totally annoying!!! It does not maintain connection to the non selected PC (on which I have multiple monitors). When I switch away form the multi monitor PC, that PC totally reconfigures the desktop to the remaining monitors. LONG time KVM user. This does NOT happen on the two previous KVMs I've used. I moved to this one because it was HDMI and had a remote.

Overall Review: Good build quality. Feels solid. Quick switching. SUCKS when one or more of the PCs connected is a multi monitor system.
