Will this work on Presta and Shrader valves?
How does the air release reading work on this?! i press the release button and air is escaping but the psi doesn't lower on the readout.
Does this work correctly with presta valves? i know the description says so, but other gauges also claim that and do not perform well with them
Does this gauge read low enough for Fat bikes 4-7 psi?

Reliable, accurate, easy to read, ergonomic shape, appears quite rugged

This is a very solid, reliable and easy to use gauge that works well for both higher-pressure road bike tires and lower-pressure mountain bike tires, and for auto tires. It works with both Schrader and Presta valves, with a simple, one-click switch to go between these two standards. I really like the large display, which is much easier to read than the tiny display I had on another, older electronic gauge that eventually failed. I also like the swivel head that makes it easy to see the display from various angles. It's got a rugged feel to it (without being too heavy for bringing along on a MTB ride), and is the proper shape for holding it securely while using. It's a great device ... the best tire-pressure gauge I've ever owned. I only have two nitpicks: One thing that's not obvious is how to use the "bleed" or air release button. If you read the instructions, you'll be fine ... so don't toss them! Another nitpick: With a maximum 250 psi, this gauge can supposedly even handle pressure readings on suspension forks and shocks ... but I wouldn't buy it for that purpose. Since this is a press-on, rather than a threaded chuck, you get too much air loss from a shock to get an accurate reading (I tried.)

Nice gauge

This gauge is a beaut. I bought the previous version several years ago, but was never really happy with that one. This new model has picked up several improvements and is a lot better. It's now easier to use, and most importantly it takes fast and accurate road bike tyre pressure reading with virtually zero air loss.If you're like me, you can probably estimate the air pressure in a high volume MTB tyre, but that's less critical anyway and the pump is usually enough of a guide for such tyres. However, with high pressure road tyres, knowing the difference between say 70psi and 110psi is less obvious from just squeezing the tyres with your fingers or putting your weight on the bike. Making it worse is the fact that most floor pumps don't have particularly accurate gauges on them, and more importantly... low volume high pressure tyres can very quickly change pressure from even a momentary air loss!The body of this new version rotates, making it simple to take readings without any mucking about or getting down to the wheel level eg. when valve is at the top, just have the gauge display facing up, simple. The gauge now fits better in the hand, and the ON button is easier to use. It takes a single CR2032 battery which fits with less nonsense than before. There is also an added air bleed button and a continuous reading mode, to allow readings while releasing air (with the gauge still attached). I always stick with PSI readings, but bar readings are also available (plus kilograms per square centimetre if anyone wants that). The smart head works well with both Presta and Schrader valves, allowing it to double as a shock or fork pressure gauge. I should mention though, that this is primarily a high pressure reading gauge (max 250 psi) and road tyre pressure readings with Presta valves are quick and leak free. Low pressure in a Presta valve tube will cause a temporary air seal leak when connecting or disconnecting the gauge... but this is NOT a fault, and it will not upset the pressure in MTB tyres unless you have no idea how to use it properly. It's the air pressure behind a Presta valve which seals it and facilitates the nice sealing around this gauge (Schrader valves depend on a spring inside the valve stem, but usually work with lower pressures eg. wheel barrow, car tyre). A sliding lever must be moved to accommodate Schrader valves, which also work just fine.Great product at a fair price, Recommended.

Flakey after 1.5 years, broken at 2 years.

The Topeak SmartGauge D2 I purchased worked well for about 18 months. I used it exclusively to measure pressure on Presta valve high pressure road bicycle tires. At about 18 months, the gauge began to stop reliably displaying pressure, taking 3 or more tries to get a readout. Also, the pressure adjustment button periodically would fail to relieve pressure. Nothing would happen when pressing the button. This was independent from the "display fail" problem. On any given try, the gauge might work as expected, or it might have problems getting a reading, or it might get a reading but not release air when the relief button was pressed. In other words, it became an unreliable faff. About two weeks ago, 2 years & 2 months after purchase, the valve select lever broke, causing the gauge head to massively leak air when tryin to take a reading. Basically, the gauge was non-functional and I threw it away.I assume it was accurate but have no means to gauge accuracy given I didn't have another "known to be accurate" gauge for comparison. I liked the large, easy to read display but I would have liked for the gauge to have lasted longer. I've replaced this D2 with Jayco's MBX-60 gauge. Though the MBX-60 uses a more difficult to read (for me) dial gauge, the old-school dial pressure gauges tend to be more reliable because they're simpler. For contrast, I bought the Topeak D2 to replace a dial gauge I bought in 1988 and that I had to finally retire because the seals were shot and could not be replaced. The Jayco MBX-60 is very similar to my previous gauge from 1988. I'll see what kind of performance/longevity I get from it.
