The product is very effective when used as the instructions indicate. The only defect is the difficulty of getting the crystals from the main container into the measuring container.

If this didn't work I would have had to call a plumber as there was a clog beyond the pvc piping in my sink. This worked on the first try.

Only used once and cleared right up!
Nothing to help Add two bottles instead of through but blocked
Works really fast & well. Within 15 minutes, completely blocked drain (due to oil and hair) was perfectly clean.However, slight design flaws with the bottle, if the inside gets wet, the crystals form blocks and don't flow from the large container to the smaller one, I had to use a small stick to plumb (lol) the container connection, and that's unsafe.
