Review on 📏 Topeak D2 SmartGauge: Accurate and Compact Black/Grey Pressure Gauge - One Size by Mike Wheeler

Here are the pros and cons of this machine. Start with the PRO, they are very light, easy to carry in a tank top and don't take up much space. Heck, you won't even notice it there. In addition, it is easy to operate with the button and the LCD panel. Convenient swivel head so you can always position your head so you can see the display. Okay, on with the cons. First, it's not easy to sit up with your head up and push down without deflating your tires. It took me a while to be able to press straight down (as instructed) and hear the beep. If you have background noise, forget it. After learning how to press the needle, the readings were accurate but not repeatable. I was losing 1-2psi on each try and again this could bleed because I wasn't fully aligned. This is also very difficult and requires getting used to the tool. Overall I would recommend this but could use tweaks like the manual to make alignment less of a problem.
