Bueno funciona bien

It is what I needed.

I have done anything like this. It is plastic so take it easy. I had to use all my strength to push the die with a little oil. Not all will go in plus what's in the hose. It was enough to work. I ran the engine for a couple minutes. Then I changed high and low pressure switched. The slight release of pressure put yellow die around both connectors. I used my black light flashlight and it was so bright. I wiped that die off and searched the entire suburban for leaks. Happy to say, no leaks anywhere. For home use it's okay but don't expect to use it often.

Work great. I use this to injected oil to the air compressor it save the task to recover the freon from the systems

My brother has me order a lot for him and I guess it worked because he didn’t complain.

Think twice!! I filled it with an amount of dye and connected it to the low (suction) port of the car A/C, which was at a lame 35 psi. The injector immediately cracked and spilled the dye in all directions. Now the engine bay is full of sprayed dye, making leak detection using this technique impossible. It also decorated the garage cabinets, walls and ceiling. It made a mess. My garage looks like a crime scene!!

Very cheap materials used making this , my 4th time using it and it's falling apart but you cant ask for much being how cheap it was , you get what you pay for , I mainly use the robbin air oil injectors witch last but there also over $100 each , its good for at home work but not everyday professional use

This thing really surprised me. It worked very well and I was able to find the leak. Be sure and get the dye that you will need with it. pretty simple to use.

As soon as it was hooked up to the ac port it just blew the plunger out the top and the dye went everywhere.

Muy buena compra, muy útil.
