Review: BRILLIANT AND WORKS - Brilliant product if used in the correct way. I found that the signal didn't work holding the device to the alloy near the valve to pick up signal, so i found that holding the device to the tyre wall directly in line with the valve worked perfectly. Job done and all tyres re programmed and no more light flashing on my dashboard. Great device
Review: Five stars - I was unsure if tool would work on my Vauxhall Astra TPMS but it worked a treat all sensors are back working great bit of kit
