Have both - an early (3xx) brass and a later (2xxx) stainless steel.
Pros
1) good/nice/clean design
2) switch is very nice
3) good adjustable pins
Cons (personal opinion)
1) I think quality control went down from the first runs. My SS version's switch is 'notchy' compared to the brass. Brass had a gouge and lock ring frozen. (Seen a few similar complaints on FB)
2) hard to get service/parts
3) threading and size not the standard 20x1
I love both and they get a lot of use. I don't think you can go wrong with your choice considering it's too late already
cheers
Belated thanks for your response! I have now had my Chi-You for a few days, and overall I am very happy with it and enjoying it. I do have a couple or three minor gripes that somewhat echo yours. I see what you mean about the airflow control--if there is a way to adjust it, I cannot figure it out. Not a big deal so far since I don't use a Genny and I probably prefer having it fully open anyway; though I was wanting to experiment with closing it off some to see if I liked that better but was unable to do so. The locking ring is sometimes difficult to twist to the locked position without also unscrewing the end cap completely. My switch seems to work well and smoothly, but I have learned that if I try to adjust the top pin so that it is tight enough to eliminate all jiggle in the battery, the switch gets stuck so that it is constantly firing. The same thing has happened when I screwed my tank/atty on too tightly. That is probably my most serious gripe as it is not only annoying but also a possible safety hazard.
