The buckle is not as heavy as I remember them being when I was in the service, but the belt seems pretty strong.  I have been using it everyday for a couple months and I enjoy it.  Does the job and it was cheap.

TIP:  After you cut the belt to size (and you will cause it is about 50 inches long) make sure you burn the end to keep it from fraying on you.  Also make sure to leave it a bit long.  Better too long than too short.
