FIRST IMPRESSION: I am very impressed with this luxurious TPMS. It is very accurate and works as advertised. It comes with everything you need to install it and has a rain cover. UPDATE: Two thousand miles later. This TPMS system is fantastic! It's a real pleasure to just rock the bike and pressure appears on the monitor. On cold mornings, I don't have to roll on the garage floor to manually check tire pressure. UPDATE #2: A year later and still fine. I love this product! UPDATE #3 October 2016 just replaced the original wheel batteries. Just a low battery indicator. Good product. UPDATE #4 Oct 2018 - I just added a low battery icon for the rear wheel. Install new batteries in both wheels. So my batteries last two years. TireGard is still going strong. This is a great and reliable product. Additional note: I've changed the battery in the head twice since it was new, so they last about two years too. How many times have you ridden your bike and wondered what your tire pressure was because you didn't have time to check it? DO YOU KNOW HOW MY TIRE PRESSURE IS EVERY TIME I GRIP ON THE BIKE! This is a great security feature. The TPMS pressure readings are very, very accurate and checked the same way as my manual pressure gauge.
