Alot of the bad reviews on here often state the slime they got is "too sticky." But! It's a really easy fix and not the fault of DS/the company. Due to the nature of the slime base and/or weather conditions shipping to you and/or direct light versus shade, some slimes will NEED activator to bring it to its original, intended form. Each order comes with activator powder/borax, but this spray is much handier, and also refillable. I reccomend this spray for anyone buying slime. Before you post a bad review, give activation a try. Just my 2 cents.
