Bag too big for HTC HD2 - fits for HTC OneX + Protective Case - short life

I bought the belt bag for my HTC HD2.
The build quality is fine (at least what I could find so far) - let's see how long does the bag.
Because the push button for the locking tab is almost in the round between rear and top of the bag.
So far, the push button but kept properly.
Also, the magnetic closure of the bag holding the cover correctly, so that the smartphone can not fall out.
Now, however, the drawback of the bag (which has led me to give only 4 stars):
the bag is too large for the defnitiv HTC HD2. In the product description, the smartphone but was called (not the heading text but the actual description).
The HD2 is 121 x 67 x 11 mm in size, but the inner bag is about 137 x 71 x 18 mm in size (and thus loose too long 15-16mm).
The HD2 is so laid back in his pocket. So I probably would have only given 3 stars.
However, I then added a star. Reason: I have for my HD2 also a battery with extended capacity. When used to place the battery (eg when hiking, etc.) then the HD2 is about 18mm thick (then any other cover on the HD2) - and now fits through the "oversize" pocket but in the belt pouch. Second aspect of the fourth star: normal Holsters can not the headphones plug into the socket on the HD2 because most Holsters have no opening for the headphone output (also in this case so). This, however, that now is not about 15mm square in the pocket can here a (angled) plug to be used and you can also hear Musk if the HD2 in your pocket is.
Anyone who buys this bag should definitely consider the extent of his mobile phone before.
It is a pity that in the product description the interior dimensions of the bag are not specified

Update 1/24/2014:
I am now switched from a HTC HD2 on the HTC One X + - and am glad that I bought the bag. Because for the HTC One X + fits the pocket perfectly. The HTC One X + is kept safe, but you can easily take it out of your pocket.

Update 02/04/2014:
I bought the bag in August 2013 - and last week she was then broken. So in a way that only one tab is torn down and a short time later the second tab.
And then there is the part more or less completely fallen apart, because without the tabs is apparently the load on the clip too big and now it is practically torn away from the bag. Leads unfortunately meant that I have to deduct a star again.
I bought then a bag from another manufacturer - unfortunately fits because my OneX + not go, because I now still have a protective sheath around the smartphone. But in case the rated here OneX + fit in well with protective cover - what is now to move me the bag but a second time to buy, even if they only lasted half a year.
Let's see, maybe holds the second bag yes longer.
I will then probably post.

Update 08/07/2014:
Well, what can I say: Unfortunately, the first tab is already cracked, the second will soon follow. And I'm not the straps on but always push the belt through the belt clip (holds bombproof). But I think if the second tab is gone, then follows again the belt clip. Now I wonder if I should every three months to buy a new bag .......

Update 10/21/2014
Had bought a third bag - and also has held only three months. The same game as always: only one tab away, then the second, then the belt clip.
And now I go nevertheless times to look for another bag.
