Has anyone used this CO2 regulator? Opinions?

By the picture, it looks like the same co2 regulator my girlfriend has on her planted tank. It came in a co2 regulator kit. She hasnt complained about it or anything. And you should know; she complains a lot when her aquarium stuff is messed up.
 
That's the one on my tank. Have had it "forever". Works OK, just hard to adjust the needle valve. If you have it on a controller--then it does not really matter.

I am happy with it.

PS--Buy some rubber "O" rings. They get destroyed whenever you change CO2 tanks.
 
Thank you all for the helpful comments. It seems from the review on TPT that you can replace the needle valve later if you need to, and that is the biggest complaint about it.
