Drano Pro Strength Foamer 17-ounce (8-pack)

Bought it because the bottle says "Guaranteed! or it's free." It was twice as expensive as it should have been for half as much product. Which means I paid 4X what I expected. But hey, if it works and it's guaranteed, then I'll try it. IT DIDN"T WORK--not even a little. Used it according to directions: Pour in. Wait an hour. I poured boiling water down. The clog is as bad as ever. I can't find anywhere on the website to claim my refund.

My double drain kitchen sink ( one side with disposal) became clogged. I bought two bottles of the Dual-Force Foamer ( one for each side). Followed instruction and it worked like a charm. Make sure you wait the entire 60 minutes and you flush with very hot water (I heated mine on the stove to just below boiling). Thank you Drano.

My kitchen sink was draining very very slow. Bought this product to see if it'll work, to my astonishment after I waited for an hour flushed with hot water and omg water went down so fast. I've never seen my kitchen sink drain with that tornado swirl before. I will buy this product over and over if needed.

I received product reimbursement in exchange for my honest review. Drano has always been my supplier of choice for any drain related issues. I had never used this type of it though and was pleased with the results. It seems to work well and get the job done. It does have a fairly strong odor though so just be aware of that. It may work best to use it and then be gone for a little while.

I received product reimbursement in exchange for my honest review. cool product although it didn't fix my problem. I can see my tube doesn't have as much water standing. going to purchase another and see if the water level go down more. Will post an update.
