I really love this keyboard! I have an advantage2 and love that as well, however the aesthetics of the advantage360 were obviously incredibly appealing to me along with the split keyboard side of things. Currently working on finishing my setup which is quite unorthodox yet works perfectly with these. I have a keyboard tray attached to a kitchen counter (I'm a software engineer who basically just codes nonstop I don't do much cooking lol) and from that I have another smaller mouse pad tray coming off for a trackball mouse. Currently have two more mousepad trays coming which when attached will be able to hold the two sides of the keyboard perfectly, and at the perfect height to allow me to have my hands in as near a perfect resting position as I could hope to get it, allowing me to use my armrests while typing in an extremely comfortable fashion.
This keyboard has basically just perfected my setup and I am beyond happy with it. I got the basic version because I didn't need wireless, even the wired version is trivial to carry around, so I didn't see the benefit there really. Worst case I'll get a second for the office once more are in stock. I got extremely lucky and searched for this on a whim on google and found the Jestik entry there. Happy I stumbled upon it and ordered, didn't expect it to sell out so quickly. I did replace the home keys with my advantage2 keys because they are shaped slightly differently and catch your fingers, but that's a personal preference (I also like the blue on those keys, looks pretty nice with the advantage360)
