Topeak D2 SmartGauge

Excellent

This product is really wonderful, as it meets both types of requirement for the user of Bicycle, easy to carry and use in all weather conditions, indeed, an accurate & compact device.

I love using this. It's so convenient, easy and useful to have. I have three bicycles (with three different types of valves - Presta, Schrader, Dunlop), one motorcycle and a car. This fits them all. Literally one size fits all. Once while riding my road bicycle I had to repair a puncture on the road and fill up the tube using a small pump. I didn't have any gauge to check. Upon arrival I checked the pressure on the gauge attached to my floor pump. It was 20 psi. Dangerously low for a road bike. I could've easily got another puncture before reaching home. That's when I decided to always carry a pressure gauge during my road biking trip. The puncture repair kit is incomplete without this. This solution from Topeak solved the problem of having to keep two different types of gauges for two different valves (Dunlop and Schrader are similar from a gauging or filling nozzle point of view and are considered as one, Presta being the other).I would've preferred a small pouch to put it in. I wouldn't put it naked inside my saddle bag which has other hardware that can potentially scratch this little beauty. I have asked my daughter to stitch a small cloth pouch for it. A screen light would make it perfect but perhaps push the price up. Disclaimer - I didn't buy it from amazon.in. Someone brought it for me from the US.
