I recently purchased this digital tire gauge to replace my old Accu-Gauge round faced, push and hold analog tire gauge. The Accutire MS-4000GB is a great, easy to read digital gauge. You press and hold the gauge on the tire valve and it "stores" a nice, easy to read, backlit digital readout of your pressure for 10 seconds. With 0.5 lb. increments, it's easy to fill all 4 tires to the exact pressure. Highly recommended, it comes with lithium long life cells and a nice case. Great stocking stuffer, priced from $18 (ebay) to around $25 (Amazon). Now after I clean and apply 303 to my tires, I can check the pressure.:up
