I've bought two different types of ratchet straps and this locking knob is a lot easier to release. I took a picture from the side to show the style of the locking knob. It works much better than other styles. The ratchet strap makes adjustment easy for your convenience. My waist is 36 inches and this brand (CIEORA) fits perfectly without having to cut. This is my third belt I've bought in a month. Excellent price.
