hi buddy!
i use my tm warthog 3-4 years now and the problems that i encounter it was that the devices it doesn't work on usb 3.0 once i try to update firmware!!
the solution was to update them to my laptop on usb 2.0 ports and then i just plug them to usb 3.0 again and everything works great!
second problem was that the stick after some time may start to produce a slack on the center on both axes as you can see here
i even replace the whole part inside the base plastic ring,o'ring,white ring along with the screws,big spring but the problem still persists.
now mind you that is only my personall experience with TM.
Others may not encounter any problems at all!!
the tm warthog is one of a hell HOTAS so if are on fire to buy it or not i say go ahead and buy it!!
ps.
(i have plug them on usb3.0 since first day and never unplug them)
