Ross R from Indianapolis, IN said, "Great product with easy installation since most everything is included in the package minus a few extra feet of wiring for the sending unit. I must warn you that if you plan on keeping less than 110 psi in your system this gauge will start blinking. This is a good feature for some but you can imagine how annoying it is for someone who keeps less than 110 psi in their system. I looked at the product details on this web site and it has no mention of this small detail. All in all this gauge has a nice display and I would recommend to anyone who likes cool gadgets like me. :)"
