I tried every home remedy and liquid drain cleaner that I could find. Dumped baking soda or baking powder, maybe both, and vinegar down the drain. My roommate who is usually the home improvement guru used a toilet plunger--gross. The plunger would solve the problem for one or two days max, then back to standing water. Nothing was fixing our bathroom drain issues in the sink AND the tub. The tub was getting so bad that it was dangerous to stand in the shower because the gross scum buildup made the tub so slippery. After I'd step out of the shower, I'd separately rinse my feet with soap and water, then step onto the tile. I was showering at the gym, rather than at home. I'm getting bad memories thinking about this and thinking about all the ways having a drain that doesn't work impacts your life. Then I ordered this. I was convinced we were going to have to hire a plumber to rip out the whole bathroom to find the problem. We dealt with these horrible drain issues for months. I took this thing out of the packaging and immediately was unimpressed. I don't know what I imaged, but the "legs" are so small, you can hardly see them. It feels cheap. I've never solved a drain problem before. I think that I followed a youtube video and inserted this thing into the drain, terrified that it would get caught on something and then my landlord would be pissed. I inserted this thing as far as it would go, I was unable to do a 360º circle with the tool. I slowly pulled it out of the drain and.... I could not believe - it didn't get stuck and all the disgusting gross crap that came out of the sink drain!!!!! I should have been wearing a rain suit with a SCUBA mask and I definitely should have moved our toothbrushes away from the splatter I wasn't expecting. Gross. I reinserted this thing back into the sink drain about 5x. I used gloves to scoop up the gunk into a trash bag. I repeated this process in the bathtub drain, using the same FlexiSnake. I could not believe what and how much came out. I sent photos to my roommates so they would think I was a genius who spent hours fixing this problem and they'd be grateful and buy me dinner. But, honestly, it took about 5 minutes. (shhhh) After using this, I spent an hour thoroughly cleaning the tub and sink. We waited far too long to solve that drain problem. Then I took a long shower, spending most of the shower looking down at my feet watching the water immediately go down the drain. I cannot believe how well this thing worked!!!!!!!!! It has been about a month since I used this thing and every time I shower, I am still impressed by how well this thing worked! As another reviewer stated, I also threw this away at the end of cleaning these two drains. I considered trying to save it to reuse, but it wasn't worth the cleanup or figuring out where/how to store it. I was thrilled to pay the price for this item, even as a one time use tool. I'll be happy to purchase another one, if I ever need it. In fact, if you have friends who are moving in together for the first time or know a girl with long thick hair or know someone moving into their first house/apartment/dorm, I think this thing should go in a gift basket along with other random items you can give the people you love that improves human household knowledge to help people solve the problems that everyone eventually experiences. Like onion glasses and a DIVA cup. I am so glad that I know this thing exists. I highly, highly recommend this item.
