## Customer Reviews

### ⭐⭐⭐⭐⭐ Outstanding!!
*by  on Reviewed in the United States March 29, 2026*

I read reviews for a hand full of these pumps before purchasing and was worried about a hand full of things. I have done plenty of automotive A/C jobs and got tired of dealing with rentals or an air compressor venturi attachment. I decided to treat myself and bought this to make life easier. It works great and bottoms out the manifold gauges within a minute or two to boil off any moisture. I kept it on for 45 minutes and was all worried about oil clouds and misting etc, but this did not make any mess at all, nor use any oil at all. Maybe it was the environment, I’m not sure. For reference this was in Southern California and 82 degrees outside. It’s true the provided bottle of oil that comes with this is only enough to fill the tank half way to its capacity, but since it didn’t consume any oil for the job I am still good for the next one. This pump is whisper quiet as well, so I was able to talk normal around it running with no issues and the neighbors can’t complain. The casing was hot to touch as expected, but not enough to burn at all. Build quality is exceptional, including the plastic port caps. I was worried those would be brittle and thin, but they are heavy duty. No leaks at all either, and will update if I have any issues. Overall, just a great purchase!

### ⭐⭐⭐⭐⭐ Good choice
*by  on Reviewed in the United States June 28, 2026*

Works pretty good and is a good price.

### ⭐⭐⭐⭐⭐ Powerful Vacuum Pump – Works Great for A/C Service
*by  on Reviewed in the United States June 25, 2026*

This vacuum pump works very well and is easy to use. It pulls a strong vacuum quickly and performs exactly as expected for automotive A/C work. The build quality is solid, the motor runs smoothly, and it offers excellent value for the price. I have used it several times with no issues. I would definitely recommend it to anyone servicing air conditioning systems or other vacuum applications.
