## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent product but DO NOT TOUCH the liquid!
            
*by B***E on September 2, 2019*

Opening the box I found that the plastic bag enclosing the bottle had some spillage in it and my hands got wet. It burned them and turned my skin white.  This stuff works extremely well. It kills Powdery Mildew and Molds as well as Spider, Russet and Broad Mites. I added 16 OZ to a garbage can with about 25 gallons of water to dunk my harvest branches in and rinsed in another can of plain water. Complete eradication without affecting the harvest.
  

### ⭐⭐⭐ Bad packaging; looks as advertised
            
*by S***N on August 3, 2019*

This arrived in a box wrapped with a lot of plastic. Inside was slightly wet, and as I took the plastic off there was some liquid, which sure enough stained my fingers white as high concentration hydrogen peroxide does. How hard is it to seal your liquids properly? So not happy about that.I did a quick density check and it looks like it roughly 34% hydrogen peroxide as advertised. So no complaints there.Fix your packaging!
  

### ⭐ Weeds largely unaffected by this, doubt its advertised strength.
            
*by T***J on August 26, 2019*

Looking for a weed killer that won't harm me or the environment -- diluted this to a 10+% mixture, and the weeds, after multiple sprays, were largely unaffected.  Increased the percentage of H2O2, reapplied, and weeds were weakened but holding on easily.  Switching to concentrated vinegar solution next.
