At the time I bought my Bluetooth Armaggeddon keyboard (see link) a year or more ago I looked at the Logitech ones and decided on the former specifically because it was more compact and almost an ideal size to use with a smartphone although I wouldn't make that decision now for reasons stated.

Moreover, despite being a mechanical keyboard, my 'A' key has deteriorated to the point where I have to push hard (often I only notice after the speller picks up the missing 'A'). This is another reason not to recommended it. And to make matters worse the key is soldered to the board in an awkward way (I was planning on swapping it with a key that wasn't used as much but it was too much trouble). There are other reasons too including bad (buggy) software that drives key LEDs. All up, it was a bad choice.

This stuff is always changing so I'll do another survey, also I've had good results from Logitech in the past so its KBs will be high on the list.

BTW, at the time I bought the Mk-17 Am. I'd first done a bit of a survey and I noted several comments/reviews that lamented the lack of Bluetooth keyboards due to the fact that there was little demand for them. I suppose that makes sense with WiFi availability but it also indicates that few bother to use an external KB with their phones or tablets. Thus, despite editing text on a mobile being such a pain it seems few do anything about it.

Incidentally, the mouse I use with my phone is the Logitech dual wireless unifying/Bluetooth model M590. It works well.
