Does AC Pro work? And is it safe?

YES, im not very mechanical. And this thing worked great in my 91 Honda Accord.

You snap it on and press the lever and watch the gauge till its in the green then you stop. This is an awesome product.

Yes, it works. But, you may need one with a sealer in it. That is if the A/C is the problem.

Here's how to tell if the A/C system is working. Locate the A/C compressor. It is belt driven and usually at the bottom of the engine. Make sure when the A/C is turned on, the clutch engages and spins the compressor. If that is working, there are two hard metal lines connected to it, one should be larger that the other one. The large one should go to the engine firewall, the smaller on to the front of the car to what looks like a radiator. Turn on the A/C on with the car running and feel the large tube going into the firewall. If it is cold, then the A/C is good, and there is a problem with the hot/cold blend door in the ducting

Any recharge kit can work, as long as the only problem is that you are low on R134A. Get the kit and put it in.

Sweetdaddy Rex is saying to put in 3 cans, which is much too much. If the system had some charge, it should only take one can or part of one

Go to an Auto Parts place and buy 3 cans of refridgerant, and put it in, yourself (EASY), and see if that fixes it ! (about $ 39.00 ) . At most Auto-Zones, they will put it in for you (FREE ) !
