Actually, I didn't have an opportunity to use the product because I couldn't force the quick connector into my low pressure port. It seems like the spring pressure is too much to push?! Or it just doesn't fit. Update: I tried my best to connect to the low pressure port and it just wouldn't snap into place. Bought an angled R134a fitting and plugged it into this charge hose and it worked great. The gauge was decent and I was able to get the 35psi pretty accurately. I still give this product 1 star because I had to buy a different plug to plug it in.
