Make sure you have a snug fit with your tubing
This is a basic unit that is simple to use and easy to read. I needed it to calibrate an ERV. I originally had a very hard time getting a stable reading and even using some stuffing around the tubing to make a better seal didn't help. I bought some natural latex tubing that had a better seal which made things much better and repeated readings were stable. The magnet in the back was very handy to affix the meter in a good location so my hands were free to make the adjustments. I have a second and bigger ERV to install but I'm confident that calibration will go smoothly. If I had to complain about something, it would be the case. It's pretty cheaply made and doesn't really have a good layout for the meter and tubing. But it does it's job.

Good product - recommend labeling your ports
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.

Must have tool for appliance/hvac professionals
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
