Works for me on HTC Touch Pro 2. I would have said no problems at all, and generally I haven't - it works fine for daily use, however:-
I have had a curious problem where if the phone is fully chrged while turned off, it then wouldn't recognise the MicroSd until I took it out and accessed it from a PC first. Easy to avoid by taking the card out before charging, or charging whil the device is on.
I then had my first major problem yesterday. I took the card out to flash the new Energy ROM after backing up, but then putting the card back in post-flash it wouldn't recognise it - and neither would the PC. I had to reformat and restore all the data (painful for 16Gb!). I am now going to keep a full backup regularly..
Otherwise, fully recommended after 4-5 months use.
