So far, after one week of tests, the system is tight and the vacuum gauge needle does not visibly move over a two day period of being left sealed with both valves closed. Construction is quite study and everything arrived clean and without scratches or wear except for some dust on the silicone gasket which did not affect operation in the least. The only recommendation I would make is that putting the gasket in a ziplock would be a great idea because it’s a dust magnet.
The unit is quiet and cheap and works great!

Excellent buy!
For the price, this meter is an excellent buy. I need an old fashioned look for one of my products and I’m using four different size 45 meters, two voltmeters and two ammeters, and it looks amazing!
