The Mega Slam 60 is a great system. Almost no wobble at all and extremely quiet with no rattles. The ball rebounds great and the adjustment is smooth and very easy. The assembly was easy with the exception of digging a big hole thru solid clay, not their fault though and the quality and strength is great. 1/2 inch glass is awesome. I was worried as I am a bit picky and reviewed a lot of different systems but am extremely satisfied and highly recommend this product and for the record I do not always leave a review but thought I should do to the price of this and helping others make a decision. I would definitely purchase another one and no I am not compensated for this review.
