X52 - great design, truely crappy manufacturing. I'm on my 7th stick in two years, which means I love the layout and the stick, when it's working.
First stick lasted 10 months, two subsequent sticks were porked right out of the box and returned. The remaining four have lasted between 2-4 months before becoming unplayable.
Right now waiting for a replacement stick from Saitek (I have three sticks usually in one in each stage of rotation: in use, sent to Saitek, or being replaced and returned by Saitek). Current stick is two months old and won't hold calibration anymore. Have to re-calibrate every two minutes or so while flying.
Maybe, I'll have to buy the X52 Pro and put that into rotation.
