After two uses with the drill driver, it unscrewed to the point where I couldn't reassemble it.
Additionally, the metal oxidized (rusted) and I wonder how they use metals that oxidize in a pipe machine.
If there was a 0 star option, I would give it.

Very good and does the job it needs to do. It's all plastic except for the metal tip and the part that secures the length of the metal tip. I remove 1 star because the tip that secures it when the tool is used with a drill unscrews and the drum comes loose. For its price, very good, I would buy it again

Good value for money. Good quality plastic and satisfactory steel at a length of 7.5 meters. One of its positive features is the axis to connect with a drill or screwdriver to convert it into electric! Be careful with the rotations, they should not be too high as there is a risk of injury, especially for someone who is not familiar with the unclogging process (professional). I highly recommend it without reservation!

Excellent, I unclogged the sink and bathtub manually in 2 minutes! The only downside is that you have to manually insert and remove the plunger, and if it encounters an obstacle, you have to turn the handle. But it is very easy and effective!
