I’ve tried them all and this one is by far the best.

My dog seems to prefer the 180 over the cub, but both make her pass out.
Mutt Muffs worked for about a week and then she’d just remove them. Rex specs are soft and can’t be removed by my dog.
I initially ignored the advice of some. That was a mistake. Luckily, my few random engagements all happened on grass. I had two on takeoff and one on landing. Been 5 years now with the late model system and never an issue.
I can send you a picture of the one I installed on mine, tomorrow. I wouldn’t install the early model PB. Go with the late model install. The early model system is hazardous to your health. Mine is a 1955.
