Digital LCD not working after about 30 days. Can't even inflate a high pressure road bike tire anymore, let alone a 110psi trailer tire. NEVER BUY. Cannot return, 30 day policy has expired. (Note: Even with the pump working correctly, it took 20 minutes to inflate a tire at 80psi at a low pressure of 8psi. Ram Turbo Diesel Crew Cab Long Bed Truck. Tried this once on one of my 38ft toys -Dump truck with 5 wheels tires that inflated 10psi in 45 minutes.) Like I said, $60 piece of junk. Instead, offer to buy a compressor.
