I'm usually skeptical about reviews, thinking people who complain about the smell are overly sensitive. MY GOD! The stench from the pipe is poisonous and disgusting, indescribable. It's so bad I can't keep it in the house. Although the pipe has been flushed many times and left outside to air, it retains an unpleasant smell. Now I have to go to the hardware store to get pipes that won't give me a headache and vomit. Another problem is the design of the hose nozzle, which does not close completely and prevents adequate suction. Unfortunately, this idiotic design is common to all types of miniature vacuum tools. Seal the holes with strong tape and assume everything is fine.
