Title: Engineers review - does not work
Review: While trying different options for moving product (rv refrigerators) at work, this was one of 4 suction cups I purchased. Not only does this not stick to much of anything, there is flash all around the sealing surface, making it nearly impossible to function. At this point, it is a funny looking paper weight. Buy the The Astro Pneumatic 9038 Suction Cup 6-inch, see my review there.
Is the review positive or negative?
