I charged my 1988 911 with r-12 that I also bought on eBay. Everything went as planned the vacuum pump and manifold gauges worked perfectly and I would highly recommend it for auto . I will use it on my residential AC when the occasion arises. the manifold gauges will be fine I don't know if the vacuum pump has enough power To evacuate a 3 1/2 ton unit but it was flawless for my auto

The old saying, "You get what you pay for" is spot on with this product. Although it did the job on my car's a/c, the pump cut off due to overheating after 40 minutes. I had to let the pump cool off and then put a fan on the pump to keep the vacuum going. I would recommend paying a little more money and buying a 1/3 or 1/2 horsepower pump. Also the fittings on the hoses for the manifold gauges will fit the pump but it will not fit the can tap for the Freon. I had to buy a special tool that had a dual fitting to get the Freon into the system once the vacuum was completed. Spend a little more and get a bigger pump and a better set of manifold gauges - if you can afford it.

Good quality pump. Worked well. Gauges and hoses also feel pretty solid and worked well. Comes with oil for the pump and the case for the gauges and hoses fits them well. Comes with instructions. I used once... that's all I needed it for. I would buy again if I had to. Items were packed well and shipping was fast.

According to the gauges it pulls a full 30hg vacuum. Works great! Gauges have a open-close function on the connectors which you find on a professional gauge set. The only con is that the low side connector is too big to fit comfortably on my car so I used a different connector. On cars where access is easy, that would not be a problem.

Works excellent and have already made my money back on it by 3 times what I paid for it just in recharging peoples systems I really bought it just to do my own vehicles but once people found out I had one they started flocking in
