I went through 2 X45s in 15 months (Thanks Best Buy replacement warranty!) Both lost hat reliability.
When the last 45 went, it had been replaced by the X-52. I've had mine for 18 months or so, and its going strong. Saitek hats are known for dying early, but so far the 52 is holding up much better.
Next time, though, its a CH for me.
