Review on 🚗 Upgrade Your Car's A/C with the MOUNTAIN 8201 R-12 to R-134a Conversion Quick Connect Coupler Set by Brian Samaiyar

I haven't tried this set during the return period so I seem to be stuck on this junk. Today I wanted to check the pressure in my daughter's newer car and hook up the high pressure side on the first try. Then I find out that the blue or low side connector doesn't connect at all. The small balls will not stick to the connection port to connect. I've tried cleaning it (albeit brand new), worked on the inside that moves up and down to make sure it moves, and tried plugging it in at least 10 times. I've come to the conclusion that the tolerances of the shop that made this and probably most other items are so poor that everything should be sold for scrap. I have tried contacting the manufacturer to see if I can get a replacement but there is no way to contact them. I recommend you NOT to purchase this item.
