This is an excellent set of gauges to have on hand for rainy days when your digitals aren't available. When I first got into HVAC, I started out with a two-valve set and worked my way up to the Titans. The advantage of analog is that your batteries will never run out. So, if you think you might need a backup, this is the place to go. Although it has a 3/8" vacuum hose, the bore in the manifold is only 1/4". If you need to recover or pull a vacuum on a large system, the Brute is your best bet.
These are absolutely fantastic!.
For such a low price, it performs admirably.
Excellent dials. The valves are running smoothly. The gauges are simple to read and understand. You can hang the hoses while working on the unit because they are long enough.
