The product has an impressive appearance and is made with excellent quality of materials and craftmanship. The variable size design has the advantage over the ordinary design which gives discrete holes/size designs. Unfortunately, though it is very easy to put on, the flexible/variable gear buckle design gives problem and it is very difficult to release when user tries to unbuckle the belt. The uni-directional gears work well in putting on but cause difficulty when trying to move the belt backward in putting it off; users struggle to press the release lever while pulling the belt off. It would be nice if the release lever could also sink the gears into embedded position so that the belt could be slide out easily.
