"It works fine, even with water in it, and the price is quite reasonable."
"I use the meter for measuring tire air pressure."
"This guage is doing fine and giving me solid pressure readings on my in ground sand filter system."
"To help keep water out, I installed the gauge so the face tilts slightly down toward the ground (maybe this is the trick to longer life?)."
"Last pool filter gauge lasted less than a year and cost more than double."
"Overall, cheap quality that will work for a few months."
"Installed the end of May,2017-3 months later and its already stuck and not working on my pool filter system."

"good price."
"Works great well built product."
"The joints already have plumbing tape as well which point to the attention to detail. Make sure the gage itself (on any regulator) is out of the sun for long periods of time."
"I like the steady water pressure since all campgrounds seem to have different water pressure. There is nothing like getting water thrown all over you when you turn on a faucet with to much water pressure and my husband said it not good for the plumbing in the RV with to much pressure."
"This is built solid and is accurate."
"brass threads crossed will not allow hose connection."
