Update for the fobo system. I installed it on October 12th so it's been a 1.5 months and I am still enjoying a great product. It's so handy to turn on the blue tooth and check the pressure at any time I want. This morning heading out to work it was 22F coming out of a garage of 65F. Checked the pressure using the app and it was 36.7 f-t and 38.3 r-t. A bit low for my taste but I expected it (I run 38 f-t and 40 r-t) and knew I would be adding air when I got to the office. Sure enough, when I got to work and let it cool down, checked them again and yes, the front was a bit low (33lb) as was the rear (35lb). I was expecting it and would have checked it anyway before heading to lunch but it was nice having a digital readout to confirm what I was expecting. I'm sold on the product and glad I purchased. One benefit to me is we have lots of road hazards in and around Oak Ridge....lots of nails and such strewn along the highways and byways (such is a great description of life in general). Having the system, I can quickly check when I run over something and keep an eye on the pressure along with a visual of the tires just in case I miss a puncture. QA for me as it were....
As for the low battery issues that were mentioned....on my phone at least, the app shows the battery power for each unit in addition to the temp and pressure for each fob. Mine are still showing full bars for both units for the batteries. In the package with the units, I had 4 spare batteries included. I saw that and expected the fobs to be power hogs since I had so many spares....so far that's not the case and an email to the seller revealed they did that as a courtesy. Another plus in my book
