This belt can be adjusted by simply pulling the belt buckle, I use it every day when I'm at work, when I sit down to eat I unfasten it. a little, then when I get up I just tighten it back up. The belt has 2 layers sewn together, my belt has the outer layer holding up well but the inner lining is torn which worries me a little. when/if the outer layer breaks. For me the biggest downside is the noise it makes when you tighten it, imagine a very big/noisy zip tie and you probably have the right idea. I consider this to be the biggest downside and, as you can see, pretty minor. (I deduct 1 star for the inner lining problem and the adjustment noise). I would buy it again. Yes (but I would still look for alternatives) Conclusion. Works as advertised but a bit noisy.
