Manometer with good readability

The gauge of Wika is a hit: good size, meticulously crafted and therefore easy to read.
In addition, on the plus side, a not too rigid hose, a valve plug with a strong lever chuck and calibration.
The manometer can be rotated 360 degrees. For readability determined beneficial. The recording of the pressure gauge is probably by type of construction a little shaky. First not bad. Whether in the long term remains tight, or represents a weak point, the long-term use will show.

The venting occurs by initially pulling the lever. Only when another drawing compressed air is released for filling. In fits and starts filling to achieve the desired pressure so air is discharged repeatedly. My old tire inflator with a separate drain valve knob liked this respect much better.

From the article description showed neither the rotation of monometers nor the control systems of deflation. In addition, the type of sealing in the picture does not match that of the purchased product from me. This is not so bad, but a little more effort should make the seller / manufacturer already.

Due to the weak and the product description is not optimal for me air control only four stars. Overall, I do not regret the purchase. A cleanly designed tool and at a purchase price of well below 40 euros a good price-performance ratio.

Compared to around 2.5 bar with my cheap China Tire Inflator the calibrated pressure gauge showed 0.15 bar to less pressure. My digital tire pressure gauge for around 15 euros brought it to an accuracy of 0.05 bar compared to the approved instrument.
