Bought for DH as the low profile tires on his car are VERY pressurized lol. And the last time they thought something was wrong was on a long drive home - at night: o He always has a pressure gauge handy, but even with the air pump in the shop it was difficult to check the pressure in the tires on the side seeing the streetlight :/ So, as always, I went to Revane to see what the options might be, and hooray! Here it is - perfect for a Christmas stocking :) He tried it out in the garage yesterday and said it's amazing, so now if the battery lasts - we're ready for the next dark night ;)
