After the initial anger a useful Tamper

The manufacturer indicates 50mm and 55mm. Thereupon I then ordered from Amazon.

Within the reviews can be found sporadically informed that there are 47 mm and 55 mm. I enjoyed my today (also) been measured (with the calipers at 21 ° room temperature) and hereby give my data by:

- Small diameter: 47.5 mm (see picture)
- Large Diameter: 55.2 mm
- Tolerance meter: +/- 0.05mm

Now it may be asked, to what extent 2.5 mm are now crucial - as need small diameter. My answer: very, because exactly this gap by the coffee again "escaped".

During my training as a mechanic, I would have been sent back with such a result, "home", with the comment that it can not be but that one does not comply with the dimensions in such a simple device.

For this reason there is for the deviation measuring only 1 star

Positive is worth mentioning that the tamper has a decent weight, and thus the "stuff" easily falls. The build quality is also fine and seems to lift long. There are 5 star.

The bottom line is I forgive 4 stars because you get used well after a few days on it.
