Ergonomically being let down as you the sleeve operation makes it slightly less simple to just insert the USB end in - the sleeve wants to move instead unless you prevent that with a small pressure. So its no big deal. Also on UX it doesnt really show you that it is recording. But I suspect that when you get the hang of it seeing the 5 blue flashes tells you to have faith. So the problem more is knowing that is it switched off.
I like the sound quality and the wav files are very good quality. I will write a longer term review so come back here by subscribing to this review if you want to see how it goes.
