I bought this for my 29ft road trailer to keep a close eye on my trailer tires on long trips. The setup is quite easy if you follow the instructions. Once you set the parameters for the sensors, the system seems to memorize them well. I didn't have tires exceeding any limits to talk to notifications. The only reason it didn't get 5 stars is because of the terrible display. Unless you drive at night, it's very hard to read at a glance. I followed the instructions on their website to 'stick on' the ambient light sensor, which made a slight improvement, but generally you need to protect it from sunlight to read clearly. I'll post pics when I get back to the install.
