The product you sent me is not a vacuum regulator. It's just a manifold with a pressure gauge that measures the vacuum flowing through the manifold and a valve that allows atmospheric gas to bleed the vacuum. It does not control or "adjust" the vacuum level in any way. Also, the image on Revain clearly shows another product that clearly says 'Made in the USA', however the product received is not calibrated and clearly says 'Made in China'. For the price I paid and with previous positive reviews, I expected to receive the product at least as advertised/ordered. I didn't expect to get this clean junk. I hope this was just a mistake by the shipping department, but I'm afraid that's not the case. I'm returning it and turning to another source. Thank goodness for a top notch return policy. Buyer warning!
