Minutes to install including antitheft lock nuts. Installed on my 34 ft travel trailer and no issues with connectivity. I do suggest buying the repeater as well.

Very well made. Very satisfied. I am very pleased with product and customer service and support that this company has provided to me.

Battery monitor is still full w/o setting it on the dash to recharge via solar charger. Works like a charm and easily read anytime day or nite. Although, it really isn't a problem if i can't recalibrate.

Great idea, flawed execution. Not something you want if all you want is to jump in your car and see air pressure like one i bought 10 years ago for my old porsche. Don't be fooled by the pictures, it's way cheaper in actual appearance.

The monitor is completely dead even it is placed under my car windshield the whole time to soak up all the solar power. The readout is so small it's really hard to see. Even plugged into a know good outlet will not work.

They are inexpensive but they are totally useless unless a tire center can activate them after installation. I have yet to find any auto center, mechanic or tire store that can activated them.
