I just got a TWD premium. How high is your bicycle girl ramp in the up position? Mine came with the ramp fix kit already installed. Part of that fix was a few pads on the bottom of the metal ramp flap. My ball actually grazes those pads on the way under the ramp. It barely raises high enough to allow the ball under. Is there a way to get it to raise higher? The entire thing seems kind of rickety.
