I finally got started with this and it works as advertised. I started giving it 4 stars. but I really can't find anything wrong with it so it deserves a 5. It does NOT come with a check valve nozzle adapter so you have to leave it on the tire but it runs fast enough which wasn't a problem. I drive a 3/4 ton Dodge with E rated BF Goodrich TA KO2 tires and prefer 5th and E rated tires. Both run at 80psi. I drive my Dodge around town in 60Β°C front and 50Β°C rear when not towing a trailer. It only took a few minutes to air the tires to 80psi, and as mentioned, the device worked as advertised. I want to get a locking adapter so I don't have to hold it all the time. It's uncomfortable to squat in the mud while applying pressure, but again, this wasn't advertised. The body is solid and well designed. I was expecting it to be hot, but I almost didn't feel the heat it gave off. I'm sure it'll be hot, but apparently not that easy.
