The approach is really good, but the production technology implementation has yet sorely disappointed me

Since I am a photo enthusiast and happy snapping, I wanted to finally bridge the gap between heavy SLR (Nikon, fully equipped quickly at 2kg and more weight) create and always with (Fuji X20 without flash 270g) to only one camera use. Here now offered Canon with its new M3, than to have a folding screen with touch (for who needs it), APS-C sensor as image quality was very important for me. Lightweight (500g-1kg) they had to be, so as not withered in the camera bag. Option one EVF should be given, jap, so sunny days are not the frustration factor. The WIFI story sounded too tempting, and the way of remote triggering. Here Canon has proven safety and style Funktionsbewustsein. In addition, you can now also reasonable, if not get a lot of M lenses. With the Canon adapter you then still a huge range of lens choices at the end of the flagpole. The adapter is especially by half cheaper than Nikon 1 models. Furthermore, Canon Flashes DSLR fit class (ie normal flashlights, not like the Nikon 1 series of system) on this Systemkamera- a plus.
So battery is charged and turned on the camera after about 2-3 hours charging time.
The first impression of the menu, feel itself is first a good, except that I (so after 10-20 min) always registered a click after repeated testing and wondered where this may come as.
I have the camera as normal with the right held by the handle and always when they are then engages properly, so there was a creaking or clicking.
So I looked at the matter more closely, noting the quasi below the front right where my little finger and the next press, it comes to this noise. Specifically directly where down the battery and SD card slot is located at Canon.
Here then I noticed when I opened this subject that when I normally reach with said fingers, it marginal deformations toward battery (empty or filled did not matter) comes. Here I am a bit scared and thought, so what can thin Canon not build, so that between the handle ability and battery wall quasi only a filled and seen Plastering mm (see photo).
This was then unfortunately taken pleasure for me to test the camera on, because such a design technical weakness handle by Canon simply doing better, what would have as a gain of one or 2 mm only at additional expense means? I do not want to someday grab the camera and then a crack or worse have just by grasping after several months there.
Maybe I'm just hyper cautious, but with a camera around 750 euros, as well as a camera of only 100 euros, I expect just such quirks not. If it was a Monday model, I've had bad luck, but to me it looks like that all cameras are certainly produced by this battery wall thickness towards the handle side in series or should be straight with me the mm pointer have wavered?
Now the search is unfortunately further :(
If you look at the picture, one sees the handle material (relatively thick) and the almost paper-thin battery compartment wall thickness (1mm?). Maybe with me was not only both top glued vermoldet or what I know, because the effect occurs only at the bottom. But was technically design something saved from here and even if it would not creak at the beginning, I was afraid that after repeated use of it could still come to the same sound. Bearing in mind that in this case through the adapter also quite heavy lenses find their way to the M3 (...)
The Canon was better-pity!
So I can only 2 stars awarded as such quirks / error / dirty production should be eradicated at launch.
But it should be each to get an idea about me now goes back everything.
