Very happy with it and had nice hoses upgrade
Pretty slick little unit and for the price! I'd seen other reviews where people mentioned the hoses being difficult to get onto the fitting and I imagine the seller took not because mine came with 4 hoses, 2 that look like they'd be hard to mount due to being kind of stiff and the other 2 that were nice surgical like tubing that stretched nicely over the barbed fitting and sealed up good. I used it to adjust my new gas valve on my furnace immediately after installation and it only needed a slight adjustment. I couldn't have done it without this tool or any manometer really. I took the 9 volt battery out after using as I imagine it will be years before I'll need to use it again if ever.

Did its job testing crankcase vacuum
Worked great. Used to test negative crankcase pressure in lieu of a slack tube manometer. Arrived quickly and quality seems good for the price. This isn't a pro quality device but a roughly $40 that shouldn't surprise anybody. I was surprised by the backlight and record features. Anyway seems great even comes with a little nylon pouch so you can ditch the box.

This tool saved me some big repairs
I bought this tool to check the PCV pressure on my Volvo's "white" engine. These are the engines in the front/all wheel drive models. The spec calls for a negative kPa and my car was showing a very slight positive pressure at 150k miles as revealed by this gauge. The PCV breather box needed to be replaced. This tool let me catch it early before the problem got serious enough to cause oil leaks, which could have doubled the cost of repair.

Not for motorcycles
Very sensitive. Too sensitive in fact for balancing motorcycle throttle bodies. If you need to do a TB sync, this might not be the tool for you. I ended up making my own manometer and it worked far better. This gauge just bounced around too much.
