Pleasantly surprised, worked great.

Used it to vacuum and recharge my F150. It pulled around 28 inches in less than 2 minutes. Sealing it off, the gauges didn't leak. The only negative is that these are multi-pressure gauges for different applications, so the amount of space on the gauge from "0" to "30" inches of vacuum is incredibly small so you cannot get a really solid reading. However, it was good enough. Pulled to 30 inches within 3 or 4 minutes and held it there for 45 minutes.
The pump came empty and with a bottle of oil, which you only needed about 75% of the bottle to fill it. Read instructions carefully.
The R134a connections worked and sealed perfectly. In order to attach this to a can adapter - you need to buy those separately. I purchased FJC 6030 can tap, with FJC 6015 adapter for the ACME to hose adapter.
This kit paid for itself on the first use. Even if the pump dies down the road because these chinese no-name pumps are cheap.... it will be worth it. Neither the gauge/manifold kit nor the pump is "heavy use" and likely would not hold up in a real shop environment, but you are paying a third the price.
Since this won't be a very commonly used item, I like that storage bag to keep it clean and dust-free.
