Product review (5 stars): Works great!  A few tips though...
Easy to install.  I followed the package directions with two exceptions.  First, I dry fitted and marked the locations where the two grabbers would be mounted to ensure a precise fit.  Secondly, I used wood clamps to ensure a strong and consistent bond for the first 3 hours after attaching the grabbers to the underside of my granite countertop.  This was done to ensure the adhesive strip had the best bond to the surface.  The directions say to hold it in place for 5 minutes and let cure for 2-3 hours.  If I were to do this I would need 4 arms...or two people...instead I used clamps and just let the clamps stay in place for 3 hours and then removed them and left the dishwasher alone overnight.  I can tell by touch that the grabbers are firmly mounted.  Its been about a month and they remain firmly attached.  I would recommend this product...if you're doing it yourself...have clamps.  It will make the job easier.
