RTH Button did not break on mine but one of the joysticks moved into the case. Screw (presumably ) left rattling about inside. Not fit for purpose and returned for full refund.
That was on a model GL300B controller.
This is another LINK showing how poor some of the Quaslity Control has been.

Yep, me too, the funny thing is I've probably pushed the button a total of one time. Pull it out to set it up for the summer and button is inside the remote! I'm sending it back to Dji, having issues with connection to RC as well.
