I can't access your link. Maybe it is just my computer, but if you get no responses, consider posting pics in the comments section.

Didn't work for me either

Yes please post photos. That said, it's not your countertop installers fault the cabinets weren't level...

Sorry - here are the pix of the seam problems

Looks like you have to expand them one by one to see the whole pic. Here's one showing the gap. I agree the cabinet guy should have leveled the cabinets, which we are pretty sure he did. When the counter guy left, we found several shims laying around the kitchen that weren't there before. I'm assuming the counter guy removed them and put his own prop under the counter.

Wood trim should hide that gap. If your counter top installer needed to use that many shims, then your cabinets were not level. Where would the counter top installer remove shims from? Were there shims lying on top of the cabinet already before he installed? They aren't going to pull shims out from underneath the cabinet. If you put a level on the counter top and its level, then you know it wasn't level before they installed.

Thanks Presidio. The installer didn't have the right color caulking when he came, so he didn't do that part. Did you look at the seam pix - especially the second pic if you click to view the whole thing, the seam in the backsplash doesn't seem so hot. Not sure if the seam on the countertop is within what can be expected or not. They told me 'you'll never see the seams.'
