The build quality is really very good. The One is also quite well protected, this does not mean that you should always leave it fall down.
The lining in light also helps to clean the same One, if one then has in his pocket. It can be taken out good when you touched up the device with two fingers. Otherwise, press from below, which is not always the same leads to success.
One must also get used to that one, the one with the insert button above and not suppressed permanently on the side :)
Otherwise, the seams are very well made and I think that the price of the bag will do justice. The One fits into it perfectly and the bag is a little over the top, so you can completely submerge the One also.
Height: 14.8 cm, width 7.7, depth 1.3 cm (depending on how you the fabric a little pulls and pushes.
I would buy again.
I hope that I have in mind long joy. I will report when there is something new.
