First off, I should point out that this is not the kind of belt you would use to hold your trousers up. The width of the strap is 52mm, and at the narrowest part of the catch which would need to fit through your belt loops, it measures 60mm. Not many people have belt loops that large. However, being that wide makes it far more comfortable to wear when loaded up, as the weight is spread over a much larger area of your hips.
What it is perfect for however, is as a utility belt which can then be used to attach camera pouches (of the type sold by Lowepro) or similar belt-mounted accessories. It is extremely sturdy. In fact, it's perhaps a little too sturdy to the point of being a little stiff at the areas where the velcro doubles back on itself to allow for waist size adjustment.
It can adjust from a max circumference of 106cm (42") to as small as you need (about 24").
What is a very nice feature is the double release catch on the belt. It works like a typical plastic pinch-release clip, except that there is a second button-push release in addition. This makes it extremely unlikely that you could accidentally release the belt. However, releasing the catch with 3 fingers of one hand is still very easy.
Great design, nice build quality and good value for money. Just note that it's a little chunky and inflexible, so you probably wouldn't want to wear it over light clothing.
As a utility belt for attaching pouches, it's a great choice, and a lot less than some of the dedicated camera utility belts on the market.
