Precision Tire Pressure Gauge (0.5~7.5kg/cm2)

Pros: pressure range is ideal for trekking and mountain bikes. (road-race bikes require a higher pressure).
the scale is very readable and not obsrtucted by anything.
as far as I can tell very accurate.
at least it measures exactly the same value as my pump showed.
has a memory function. meaning: it stores the highest pressure and displays it until one presses the small button.

Cons: it looses a small amount of pressure while attaching it to the valve. (the volume in the measuring chamber has to be equalized with the tire pressure)
but thats not a big problem. one looses about 0.05 to 0.1 bar per measurement in a standard city bike tire.
the build quality could be a little bit better.
e.g. the button feels not very sturdy.
the rest feels good though.

Other: looking for a device to keep track of your bike tire pressure? get this one!

Pros: it is small, it has a plastic box to store it, easy to fit in the tire, it has a feature to deflate the tire, the result gets frozen to see and it has a button to release the last result. the result can be in lb/sq.in and kg/cm2. the build quality is very good, it means to be strong.

Cons: it has a medium precision. the plastic box has broken on the first time of use. it is a bit difficult to read the result, the divisions of the numbers are very close to each other.

Other: it is a good deal for who needs to know the tires pressure, but with a medium accuracy.

Pros: · It is easy to use. · It seems to be precise (The result is very similar like what my pump shows.) · The "Hold" function (The highest pressure is hold until you push the release button) · The pressure gauge itself seems to be very robust.

Cons: · The plastic box is fragil (mine was broken on arrival, but I wouldn't have used it anyway). · As far as I can tell you can only use it for Schrader valves.

Other: This pressure gauge is most useful for MTBs or Trekking Bikes with Schrader valve. Cars normally use lower pressure so that the scaling is too imprecise. For Road bikes you need a bigger range. If you have a bike with Dunlop or Presta valve you need an adapter.

Pros: - Do what is designed for : Display pressure gauge of tyres !
- Works for all tyres : Car, mountain bike, caravans... (haven't tested others)
- Accurate and reliable : Precise measure of the pression
- Double scale, for all kind of people (PSI & BAR)
- Metal made, so it feels sharp
- Very simple to operate

Cons: As others said, the box is bad quality. Mine was borken opening the parcel... But that's not a big concern for me, as i prefer have an good tool in a poor box, rather than the opposite ! ;)
Some people in the forum have asked if there are memorie : No, there aren't, but the measure stays readable as long as you don't push the left upper button (reset)

Other: Nothing more to say, this item does its job for a very decent price...
In France, this kind of thing cost more... many more ! :)
Bonus :
BAR scale is better than others tire pressure gauges, because it's on the exterior of the gauge, so it's more readable for people reading pressure in Bars

Pros: First of all, it is accurate. Easy to use it in cars, motorcycle and bikes. It saves the last read pressure until you press the reset botton. It is well buit. In fact, it is more beautiful than the photo in the site. It come inside a plastic box, that keeps it fixed and protected.

Cons: The only thing I did not like was the adhesive tape that keeps the box closed for the delivery. The tape is large and when I removed it, it let the box sticky. Just this.

Other: Good to have among the other indispensable tools.

Pros: It´s a very nice product, compact, easy to use, it came whit Kg/cm2 (bar) and psi scales, came whit a plastic case which is usefull for keep the gauge safe from injuries. For the price is a fine product, and have a decent termination. Can be clibrated but is very dificult to do.

Cons: It´s not very acurate, but for the price you can´t expect much more. I order 3, and one came whit a big error in the measurement. I use a patron gauge to calibrate it, but after a few uses it back to the original error i think is broke the inner mechanism.

It have a easy way to calibre moving the display, but the 3 i buy came whit no margin to move the display it help if came whit more margin to calibrete easily whitout removing the needle.

Pros: Nice pressure gauge to keep in your gloves compartment. The gauges at gas stations are often very much off correct pressure, so one of these will verify the tire pressure. Gage feels light and very solid. It also keep the value when button is pressed prior to removal from valve.

Cons: It took forever to remove the packing tape glue from the transparent case, which also was broken prior to shipment - no fragments in envelope. Center of cover glass needed some display polish to become clear.

Other: In spite of for accessive glue removal I am happy with the rubber banded box in my gloves compartment.

Pros: Good stuff: small but efficient metal pressure gauge. Very easy to use: just put the nose on your tire valve and push once, it will indicate and keep the value ! press the little button to liberate the air (from inside the gauge) and the indicator came back to zero. No need to stay on your tire to read.

Cons: well for the moment no cons at all :)

Other: I've tested and compared the results with others tire gauge and it works great ! Good stuff, I like it. Very useful

Pros: It's a great product to know the exact pressure of your tires. I used to have one and I lost it. Decided to replace it immediatelly. In just a few seconds, you can know the exact pressure: just put it in the tire and then take it out to see the pressure indicated. Then press the botton and reset the clock.

Cons: None. It's a great product and very small. Maybe it should have a better packaging to deliver and receive in better conditions.

Other: Great product and great price.

Pros: able to measure my bicycle tyre pressure accurately. able to measure up to 100psi pressure . very solid built and good quality come with a nice casing for storage. it able to make my cycling life easier without the need to use pump gauge or go petrol station.

Cons: its uses shrader valve only but that only matters to presta valve rider.

Other: without the hassle of going petrol station or guessing your tyre pressure. this gadget at this price is a must for every rider.
