So far so good.
I didn't give them 5 star's yet because I just bought these in a pinch. They are working just fine, flow is good and I haven't experienced any restrictions. It's used for about 2 weeks now for several hours a days. No negatives yet other than it's not brand named.

Simple, inexpensive safety
These flashback preventers are for the regulator side of your torch set up, and you absolutely should have them in place at all times. If you’ve never had a flashback, take it from me—you don’t want to have one. For dairy cheap price, you can protect your expensive hose regulators, and in some instances your bottles from gas reversal explosions.

Two thumbs up and five stars for these flash arrestors overall while not perfect very nice...
Two thumbs up and five stars for these flash arrestors overall while not perfect very nice...I did notice that the threads needed to be demurred a little more but aside from that very nice.Good day & God Bless...Randall M. RueffK9RMR

Work great.
The acetylene arrestees are excellent quality. And cheap too. I was very happy with them, the figment was perfect and they worked great. High quality, no rough edges or threads. Just a quality part and cheaper than the fabrication supply stores.
