Has anyone ever used this Adhesive? I have always used Bostiks BEST.

My vendor has recommended it, but I am looking for an installers opinion.

Did you use it on concrete or plywood? Did it hold the ridges? Etc?

Never used it but a guarantee it holds its ridges way better then BEST!!!!
I hate BEST, because it slumps. I like BST

And BST costs LESS, which we also like.

I have used it twice and I am well pleased with it. I tested it first by gluing a piece of wood on to the concrete and went the next day to pull it up to see how good the bond was and that bad boy was stuck just like B.B. but for ½ the money$$ Me so happy
