Does it work? Sure

It obviously due to it's length, it only works over short distances, in other words the first few feet of the drain. If the hair or other debris is further down the drain it will not help. Would probably be best for a sink where the trap is close to the drain.

I would consider this a somewhat disposable once or twice time use system. (they are pretty inexpensive)
