They're well made and they'll be cheaper than buying them from the States.
Steve B aka BBB Fabrications (a forum member on here) makes them himself, unlike Lt Snyder aka desmotimes who has them made for him to sell.
I've actually had a chain let go at around 125 mph hard on the throttle in 3rd or 4th gear exiting a corner, luckily my bike was fitted with a case saver...
The chain burst outwards the carbon sprocket cover, bent the case saver, chipped the paint from my new/freshly painted rear wheel and smashed the rear light on it's way to freedom but...
It didn't break my cases (Inc' a genuine Corse Magnesium Alternator cover) and with a little bit of work with a hammer on the back of the vice the case saver was good to go again...RESULT!
Contact Steve B aka BBB Fabrications his case savers are made from slightly thicker stainless steel, LT's/desmotimes are made from mild steel and despite where they're fitted they do rust IME.
