I picked up a couple of these and I think they are great. You will probably want to cut the belt to length (this is done at the buckle end) and when cut, you will want to just scorch the cut end with a lighter to stop it from fraying and unraveling. The belt is very sturdy and the buckle works as a grip rather than "pin and hole", so is fully adjustable (especially after a big meal).
Worth noting that the metal parts have been lightly oiled (presumably as part of the manufacturing process). This did not cause any problems or mark any clothing, but when the belt first comes out of the packet there is a bit of a chemical smell to it. This smell dispersed completely within about an hour.
I am using them every day and have run them through the washing machine with out any problems (buckle removed and belt placed inside a pillow case to stop the metal end cap from battering the washing machine).
Great product. Great price.
