### ⭐⭐⭐⭐⭐ Works good, delivery good
*by M***E on June 21, 2023*

I recieved the chemical on time as expected. And more importantly it works perfectly. Maybe I shouldn't be too pessimistic, however the first bottle I purchased 2 years ago didn't work as expected. This bottles color is bright magenta when reacting. The bottles seam to seal well. My old bottle worked well for about a year, then evaporated to almost nothing in 2 months. Time will tell. I will update this in a year.
