Perfect size, easy to use and handy magnetic back.

Great if you need to measure differential pressure. I use mine for checking building pressure at exterior doors. The directions can be a little confusing. You have to know what connection port is for high and which is for low. I used a label maker to put stickers on each port so that I didn't constantly have to consult the manual. Works well enough for routine measurement tasks. If you need something precise, you probably need to purchase a device that can be routinely calibrated by a testing lab that can certify the device at least annually.

Works as it should. I've had it close to 12 months and works fine. Of course you'll need different hose/tubing options for your job site. I use it for gas appliances and the ports are around 3/8 or larger. Still a great tool to have dual ports inh20 ,zeroing feature, magnetic

Works perfectly in setting upto gas pressures in gas valves. This is a MUST have device to keep your installations safe and operational.
