Works awesome! Follow directions, and you'll be fine! I had a major grease/hair clog since my kitchen sink runs into my tub. Have had a plumber here a few times who always ends up using a product similar to this. After numerous attempts with a less toxic chemical, we decided to try this. I ended up using the whole bottle, but my clog is gone!

This product is excellent. And to hook up the sprayer, which is automatic, no squeezing it just runs with a motor triggered by a battery. It was easy to put together. I've never had such a great weed killing apparatus. I highly recommend it for weeds.

Best drain opener I have ever used,

This is the best drain opener I have ever used. My kitchen sink gets slow at times and I have tried multiple different drain openers. Most I would have to leave overnight and use more than once to get it fully open. I used liquid lightning and left it for 30 minutes and it was fully open . It doesn't take much either. I would highly recommend.
