It was heavier than I expected, leading me to believe it's built a little stronger than I thought it would be. It's perfect for a home environment, definitely not a professional one. I can't imagine the sensor surviving more than one drop. I didn't list anything about it, but it does have a deflation valve in case you over-inflate your tires. The cartridge for mounting on the valve stems is OK. The release lever on the chuck was interfering with the wheels on my wife's car. It also doesn't seal very well if you're using it at odd angles and need to bend the hose. The gauge appeared to be as accurate as a traditional blowback gauge. It didn't come with thread sealing tape like the others, but I didn't really care. It seems to me that by the time you buy this you probably already have thread seal tape.
