Bests & Worsts Reviews from Amazon

I ordered 2 of these Tekton tire gauges and one was DOA. Upon investigation, I found that the DOA was caused by a dead battery. I changed the battery and it worked. Just for reference, this uses the CR 2032 batteries which can be purchased for about $1.50 at Fry's electronics or even Wal-Mart. Testing the unit I was pleased with the small light on the front, as I could locate the tire stem pretty easily in the dark. Don't get me wrong, it's not a flashlight but a pen type light. The unit was a bit fickle as I tried to test the tire pressure and it had a hard time getting a good seal which lead to minor air leaking. When I moved the unit a bit it would seal up and take the pressure. I tested it against an old handheld Slime model and the TEKTON was 10 PSI higher or my Slime was 10 psi lower. I'll take it to the tire shop to get an accurate reading on both and report below. The unit itself is nice, the backlit display makes for easier reading. The battery was easy to replace but the angle of the TEKTON is a bit off, it is Left angled so depending on where your tire stem is, it can be a bit difficult to attach. Please note, this is for right handed people as the unit's display is turned backward if trying to use left handed or when the tire stem is to the far facing right it will be upside down or you have to stand and rotate to line it up. UPDATE: I am sad to report that I took my car to the tire shop and they confirmed that the TEKTON was not accurate, as it was off by a whopping 4 PSI for one and 4.5 PSI for the other. My old slime model was off too, leaving me without an accurate tire gauge. I'll have to return these for a refund, luckily I'm within the 30 day cutoff for Amazon returns. I can't and don't recommend this product. Vidimo Se!
