Blitzluft 280psi valves

FBI is having their buy one get one free sale so I'm thinking about picking some of these up valves. What is everyones opinion on them? I did a search over on ssm and many people said they liked them but a couple people said they had problems with them leaking. I don't have a whole lot of cash so I figured if they were worth it I would pick some up to get me by for a while. Let me know what you think.

I have the regular blitzluft valves for my up's there awesome if u ask me, I also might order some just for back up's...

I almost bought them and swapped to SMC's. No reason, except I know SMC has been around a while.

hey i looked at them on FBI and it never said what size do yall know ??

well never mind there 1/2" but they didnt say before

Looks like I'm going to order some next week. The price is right and it will give me something to start with now all I need is some bags the rest of the stuff.

i think i might buy some just for another project i have 8 new smc's sittin at the house too but those are goin on the truck right now
