I bought a US General Harbor Frieght leakdown tester and that thing is full of ****! I bought it to check my leakdown but that thing only holds 5psi of air pressure when the right gauge is zerod out. The result is that the needle NEVER leaks pass zero. I have searched youtube and have found many people who are having the SAME problem with this exact tester and I would not recommend anyone to purchase that brand. Now I need another tester and do not want to fall in the same boat again. I have a choice of three testers:
1.) Jegs tester
2.) Proform tester
3.) Longacre tester
For those who has experience with any of these tester, please chime in and tell me if they were any good.

 

Long Acre is ok.

We only use the Snap On products for those testers. They seem the most
reliable. Granted you can get cheaper ones, But I like to have the
confidence that our will work when we need it.

 

i want to know too, i wasted the 35 bucks on the harbor freight one as well

 

I was going to buy one of these harbor freight leak tester..thx for the tip
