I have obtained one of these from Amazon Vine to review. Lovely remote! It worked perfectly apart from one thing. It understands about the 6 Humax configurations, and tests your remote to see which you are using. Unfortunately, it then ignores the result, unlike the Harmony 900! So, when I want to watch my Freeview+ HDR T2, my Foxsat HDR springs to life! Very disappointing. So, the only way to use it with multiple boxes seems to be to teach it every command on one remote. Apart from that, ergonomics are excellent, with a large touch screen with swipe scrolling, fewer buttons, but those all important colour buttons are there, unlike on the Harmony One. The battery is sealed, unfortunately, though it may be possible to open the case. One thing missing that the 900 has is that RF signal to an IR repeater near your equipment. Oh, and Merry Xmas to all!
