Good quality, stupid mistake

This is my 2nd bracket for S2, which I use when cycling as Navi. It was important that - except obvious characteristics such as strength and durability - assembly and disassembly is quick and straightforward (with frequent breaks for shopping) and that the device can be charged from the hub dynamo while driving. The latter I deal with the "E-Werk" of B & M.
Without recharging the battery the activated Navi display holds out perhaps 1 hr.

The housing encloses the Samsung very solid, the material makes a very good, stable and well-made impression, display and cameras film window operation by the front foil works well.

What is completely incomprehensible to me: at the bottom, where the S2 has the USB port, is a round recess (!). So if you have a Samsung S2 with Mini Jack-charging socket, which can use it without any problems.
I can only, the hole with a file to enlarge. The rubber seal - also well made, so pushbuttons function properly - but is so thin that it is already torn during removal on the site.

With enlarged hole for charging cable the hermetic seal is no longer guaranteed. With little rain there is still the hope that upon oblique mounting the water does not seep into it - I have to test but still.

Too bad - solid processed, high-quality material, but stupid mistake in the specification. Otherwise it would be full 5 stars.
