This is a great snake for toilets, and seems very well built.
We have had to plunge our toilet for years, and it always worked. After 4 hours last night and 4 blistered hands I needed a different plan. (Yes my wife plunged too. Our rule is you plug it, you plunge it). After lookig at what was available at HD, I realized I needed to search on 'Toilet Auger,' and not just 'Snake.' My first impulse was to buy a drill powered snake (Urr, as Tim the Tool Man Taylor would have grunted) until I saw the reviews that said you can break your bowl with them. Hence "Toilet Auger.' Of the brands listed, this one had the best, one-sided distribution of love/hate reviews so I bought it.
I didn't watch videos since I've done some plumbing, and didn't really need too, once I figured out the combinations of motions needed: Going in - push til it resist, rotate and push, push. Coming back out - pull til it resists, rotate/pull, pull. It helped to pull the whole unit out a little sometimes when it got stuck coming out, and then slide the handle/tube unit back into the hole over the snake. Don't pull it out too far though so you don't scratch your porcelain.
Please also note that turning it one way is more helpful for making the snake go in and out. I don't remember which, but it depends on the way the snake is wound. Try it one way or the other as you push it in or out.
The reviews here were very helpful, and I picked up 2 important pieces of information. Slide the snake all the way into the tube/handle piece before putting it into the bowl so you don't scratch the bowl. When you buy it the snake is extended, and I can see how you can miss this important piece of info. It took me a minute after I took it out of the packaging to see what they were talking about, and the light went on in my head.
The other advice was to get the 3 foot unit. A reviewer talked about the problem they had working a 6 foot unit, which is when the other light went on, because the 6 footer is so tall. Looking at my toilet and based on my experience, I couldn't get down into the waste pipe anyway, even if I had a 6 foot unit. If the clog is below the toilet in the waste pipe you should take the toilet off first anyway, and then you'll have a straight shot. Hopefully you won't need to do that, but if you do, you should be able to eliminate the toilet as the source of the problem with the 3 foot unit before having to disassemble your toilet.
Here's a caution. I also bought a new-style plunger with a nice T-handle, which I hoped would work better than my old one. Unfortunately it worked too well! The seal with hole in the bowl was tight which forced waste water into the toilet tank and sucked water back out of the tank into the bowl! I don't like that! I don't think it will contaminate my supply line, but be careful...
