This worked for me.

I've read other reviews and wondered what people expect for $79 these days? This vacuum pump works as designed. No, pump oil is not included. For my use (vacuuming a car AC line) it got to -30 HG PSI on my system in just a few seconds and stayed there as long as it worked. got it for the same purpose (twice on the same machine and 2 other machines) and it worked flawlessly. The noise level with the oil cap off is loud, but that's not how it should work. With the right amount of oil (at least on

Works well, easy to use. Ideal for car AC charging.

Works well to create a vacuum in a closed system. I use air conditioners in cars to refuel. I used to use a cheaper option from Harbor Freight. Without a doubt, this is an excellent method. It claims to draw 4.5 cubic feet per minute. I haven't tested the specific drawbar but don't worry it does what it says as it would drop the AC system to over -20bar if required. What I like: 1. Works as it should and is not very noisy. Nothing else really matters. Things to know: 1. Comes with a minimal…

There's oil in it, but not enough. There's even a sticker saying not to use until oil has been added. Maybe it's just me, but I find it frustrating. The last vacuum pump we had was with oil. And it's not like most people have vacuum pump oil at home. You? And not that you can buy vacuum pump oil anywhere locally. I also wonder

Good pump but no required oil

PROS: + Dual outlet + Large oil sight glass + Quiet + Built in thermal protection CONS: - Required oil not included, single stage level pump. Once I had the right amount of vacuum oil and followed the instructions for adding and breaking in oil, I was able to quickly pull the vacuum on the A/C in my 4Runner. I've attached a video to demonstrate how fast it works. It was very quiet compared to any other vacuum pump I've used in the past, which is a nice feature as you really should leave it on…
