Review on Inspired Designs Nano ➿ 2.0 Ferrofluid: Enhancing SEO-friendly Product Title by Jason King

Something dark and oily comes out of the bottle. I thought it was a holdover from production but I cleaned it up and after a few hours it was a mess again. The oily substance also appears to float on a clear liquid. It's non-magnetic. I bought this for my husband for Christmas, but of course I can't give it to him like this. Disappointed. UPDATE: The seller got it right away by sending a new bottle which is perfect. Great customer service, interesting product!
