BWSHLF Tubeless Presta Valve Stem users

Anyone use BWSHLF Tubeless Presta Valve stems?
Pros/cons?

Saw them on Amazon & looks like there are about 5 other brands that look identical with different names but the design is cool–holes in the bottom to let the Sealant flow through easier…

Just get Reserve Wheels Fillmore high-flow no clog tubeless valves and be done with it. Never had any issues with them after several years of usage.

Thanks.
I was going to get Stan’s universal but checked into these & while they are more than most–looks like a good design to seat tires if you don’t have a compressor (which I do), but may not if traveling. High volume air input too…ordered!
They actually got better reviews than project 76 as well.
