I've had the Baggershield for over a year, it is great for summer riding solo, and easy to change to high for 2 up riding, to me this is the best shield by far. be sure to get the wider version which helps keep the wind off your hands.
sorry to hear about taters problem, my son sells replacement parts so I can get her a new knee wholesale, the only problem you have to install it yourself.
Taters
good luck with your recovery.
