Topeak SmartGauge D2 Digital Tyre Pressure Gauge

Fine device! Works as you might expect....

Pros & Cons

Fantastic little piece of equipment - I use it regularly to quickly check the tyre pressure.

I was looking for a product to monitor pressure that was accurate and pocket-sized, I think this pressure gauge is very reliable and convenient

Pros & Cons

Fine pressure gauge in PSI approximately accurate to 0.07bar. Head is rotatable in several positions and stays well on valve. When discharging, pressure does drop more than it actually does.

Pros & Cons

Fine compact pressure gauge. Build quality seems fine and measurement matches calibrated Michelin gauge. Continuous measurement is very handy and can be used to get tires at exactly the right pressure. First inflate it a little too hard and then deflate it incrementally via the pressure gauge in continuous measurement mode until the desired pressure is reached. Switching between French and auto valves is quick and easy. Please note that a 28mm road bike tire loses about 0.2 bar of pressure when coupling. So I mainly use the gauge to get the tires to the correct pressure. With a car tire, the pressure loss when measuring is negligible, so it can be used for checking. Device would be even better if two decimal places were measured and displayed. For example, the recommended tire pressure for the front tire of my motorcycle is 2.25 bar. As a result, I now have to choose between 2.3 and 2.2 bar.
