Title: Double Beware!
Review: I bough mine at Lowes and I'm returning it the same day, as it didn't unclog my drain.This concept will only work if the restriction is between the sink and the first Y in the plumbing. If it is beyond the first Y, water and/or air will just head the other direction at the Y, rather than towards the restriction.No matter how hard you push down on the device and try to create a tight seal, water is going to splash everywhere. With a double kitchen sink, you have to have someone push down on a rubber stopper to try to prevent water from spraying up in that direction. You will both be soaked after using this; even with towels in the sink to absorb the spray. You will need a shower after using this device.
