After a lot of research and comparing this to the "equivalent" Pro Dunk and Goalrilla systems, we bought the MegaSlam 60". We came upon the MegaSlam by recommendation of our friends and a local hoop installer. As we were told, this is the best built, sturdiest, in-ground system available. The entire product is built from high quality materials and it is obvious the designers carefully considered stability and weather resistance. The post and backboard are rock solid, adjustment is via a feather-light crank system, and it looks amazing in the driveway. Ordering, delivery and un-packing were very smooth. I highly recommend the MegaSlam....BTW, there's a YouTube video comparing the MegaSlam to Pro Dunk....watch and you'll see the difference.
