I tried a large tub of it. It's very average in performance but cheap. I was glad when it was used up and didn't reorder. On the positive side, it's cheap & doesn't have a ton of optical brighteners like many popular encap products. The worst issue is it can leave a white powdery residue that doesn't just vacuum up. You have to run a
CRB over it and then vacuum when that happens.
If you have it use it but it's not something I recommend with so many great encap choices : Vacaway,
Harvard Bonedry (recently reformulated & much improved) and DSC Spin vac are my personal favorites. All three work wonders.
