The people who praise the operation of the X52 because they haven't had any problems yet are correct. The people who are unhappy with it because they have had problems are also correct. It IS cheaply constructed, so it's luck of the draw if you get one that lasts, or even works.
Works great while it works, until it dies; This is the second one I've had, for more than a year now, and it's still working fine; But...
The first one lasted about 2 years, then started with the blinking blue lights, and not working; I read all the forums, did all the uninstall/reinstall drivers, alternate drivers, registry hacks, plugging in and unplugging in this order and that; Nothing had the slightest effect.
