Review: Perfect size, easy to use and handy magnetic back.
Review: 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.
