I've been using the keyboard for about 3 weeks, and I have to say, it might be the single best keyboard purchase I've ever made (and I've made lots!).
I own a Filco Majestouch 2, the full-sized, USB version, so I knew generally what I was getting into. It's a quality, no-frills, professional keyboard. If you used any of their keyboards, you'll know what to expect; all their products are of the same caliber. This tenkeyless version is great for having the mouse closer to your body, and I've purchased a separate number pad for when I need to input numbers extensively. It's great to have the number pad when you need it, and can be removed when you don't.
The bluetooth connection is typical, in that it has the flaws of every single bluetooth keyboard I've used. It takes about a second to connect, and it'll enter sleep mode if you haven't used it for a bit. Again, this is expected and I don't discount this keyboard for it. It's a solid tradeoff for extended battery life. Otherwise, connection is excellent, and I'm able to use it at a normal distance (though I haven't tried across the room, as I haven't had a need for it).
The most important feature in my opinion is the multiple connections, up to 5 if you're including USB. This lets me type on my iPad, my iPhone, and my PC with a quick keyboard combo press while I'm at the desk, or move it to my couch and use it with my PS4 and Raspberry Pi on the TV. It's absolutely fantastic. Originally, my search was for a normal bluetooth keyboard without this feature, but having this has changed my view of regular bluetooth keyboards. It makes it so much more useful.
One very minor thing that bothers me is the placement of the volume keys. Why it's reversed from every other keyboard, I'll never know. Every other keyboard has, from left to right, the mute, volume down, and volume up; on this keyboard, it's volume up, volume down, and mute. I'll often find myself muting by accident when I try to increase the volume, or increase the volume when I try to mute! But that's a minor detail from an otherwise perfect keyboard.
All in all, a fantastic purchase. And Keyboard Company shipped it in a time I didn't think was possible from the UK to Canada. It's always a pleasant surprise when buying from a reputable dealer and recieving the item at a break-neck speed.
