Misinformation & Generalizations are equally annoying. "Manny" is the contact name on Alibaba, the website. Doubt "Manny" exists with that name for real. Here is what "Jinhua Manufacturing" says about themselves. Huztl is the eBay store front for that manufacturing operation.

Now MY personal experience....
So far I've had pretty good luck with parts that have the Farmertec brand. I have an interesting pair of MS660 cylinders. One actually manufactured and sold by Jinhau Farmertec and another from a Chinese trading company that does in fact source part from a variety of manufacturing outfits, including Farmertec. The one cylinder (Huztl/Farmertec) is a pretty nice part. The other..... obviously NOT made in that same mold although to an unpracticed eye you might think they are, is an unusable part in my mind. Which is why if its from China, I want to have the Huztl store and Farmertec box because to this point in time the parts have in fact been consistent and I've had a lot of fun for not very much money building saws and running them with those parts. So I'll throw my hat in the ring. And Until I actually see evidence of the horrors assigned to those "Huztl" parts...I'm going to continue using them in my project saws for my use.
The reason I brought up the "two cylinders" is it took me a while to be able to recognize the differences between many of the cylinders, especially for the 372's; that came from multiple marketing channels and actually LOOKED very much alike. Especially on eBay listings... But I was shown cylinders that had failed and LOOKED very much like the parts that came from Huztl...but I now realize they first did not, and second the places that sold them have NO idea who in fact manufactured those parts. I'll see if I can upload pics.
