Review title: Ineffective
Product review: This gadget did not work for me. Sure, it sprayed around a lot of water but it failed to dislodge any blockage in the kitchen sink or bathroom tub. The whole CO2 cartridge and "power disk" thing is just a gimmick. I used all the supplied cartridges and disks as well as another package of same and did not obtain good results. While the idea using of forced air to clear a drain is a good one, I think it's better to use a device that you don't have to buy expensive replacement components for. I'll try the hand pumped models next time around. Or just call a plumber!
