I'm starting to really like Boulder Tools products! This is my second and also the winner. The sensor is big and sturdy and definitely not flimsy at all. The sides are covered in rubberized material to protect it in case I drop it, which is probably due to how clumsy I am often. The stem is short but fits easily into tight spaces, and the end that connects to the bar pivots so I don't have to hold the sensor at an odd angle. It's analog, not digital, but I still found it very accurate and easier to read than cheaper tire gauges with a stem that pops out from the bottom. And on the side of the bar there is a handy button for deflating. You don't have to flip it like the cheaper sensor. This is another solid product from Boulder at a very reasonable price. I will almost certainly buy from them again.
