I tried Q suite a couple of years ago. Paid for reserved seats cancelled due to plane change with no warning, and no refund, after they at first agreed one. Seat not working, one of the toilets not working and for the first time on any airline special meal did not turn up booked months before. Add to that waiting on the landing bridge for 35 minutes in the heat while they got the plane ready and that's me done with Qatar, Emirates or Eva in future. They did have plenty to drink, but terrible value for money and customer service.
