Water Wiggler

Water Wiggler is the sort of novelty toy or pet accessory that leans on motion more than function, so the appeal is immediate and narrow. By our assessment, its strength is simple visual restlessness: it gives a small, wobbly effect that is easy to understand at a glance. The downside is also simple, because items built around one gimmick usually run out of interest quickly and do not do much beyond that motion. In practice it is the kind of thing that matters most when it is moving, which means it depends on novelty and on whether the person likes that kind of fidgety object. It sits closer to cheap impulse-buy gadgets than to serious equipment, and that makes it a light, limited purchase rather than a lasting tool.
