Zip-it/Hair Snake
I usually dislike single-purpose tools. Single-purpose tools are either for tradesmen who do the same task repetitively, or they’re appliances that can’t be used in any other fashion.
One exception to this is the plastic hair-clog drain cleaner. It’s only useful on drains that have clogs of hair or other fibrous material, and you must have one in your abode, unless you and everyone who showers there is bald.
