For balance I’ve had one for a while and its been fine.
Depends what you want – a bit more protection than a normal helmet or a proper full face as it’s definitely the former. I figured it’s German and therefore must give some certificated protection level.
Only used it once in the alps and a couple of BPW trips although I might take the chin guard off now to replace my day to day helmet and go proper full face if I make it to the alps this year. I did pack it out with some spare pads round where my jawbone hinges to make for a better fit. Had one spill at BPW and it saved me some cheek/chin impact although that was a glancing blow off the Pork belly rocks rather than a straight on impact.
