Well I generally don't buy anything critical to engine life like cylinder , cranks etc but at least I thought they could get that right, like I said it's all about the amount of $ they pull in and have no reason to improve as long as people keep buying it-- tried getting some satisfaction on 372 boot clamps that were pictured like the proper oem ones and they sent me household hose clamps 3 times in a row and said that their engineers said it was a good thing and I replied maybe the should get some new engineers... my time is a little too valuable than back and forth emails going nowhere and besides even if I did get some new cases from them I wouldn't trust using them, - having to pull down 2 saws because of these it enough to make my faith in them around zero.
