Question: How much cement is needed for installation?
Document: Everything I was looking for in an outdoor basketball goal. Some complaints say that it's nothing like playing on a real basketball goal or it shakes to much, etc. Well, it's an outdoor goal and nothing more. It's a top quality goal and plays well. Sure it doesn't bounce the way a real goal does but it's also made to withstand the elements. It does take the time specified to assemble and you will need 2 people towards the end of installation.
It was not too difficult for installation. We did use about 9 bags of cement, but it is really sturdy. Besides the wait time on the drying of the cement, the instructions were easy. The hoop is great and slam dunk friendly.
This was a present for my grandchildren. They are getting so much joy from it and it is such a family pleasing thing for them all.
Everything was intact and pretty well packaged. I did have a few things floating around in the box where they shouldn't have been, so I would recommend taking inventory while you are still in the return period.I was able to assemble this by myself without too much frustration. I wouldn't recommend doing the final few steps of the install yourself unless you are tall and strong like me or like hernias, but it is possible for some people.
Other reviewers mentioned rust after 5 years. My realization is that to get the quality I wanted, I'd have to spend much more. I returned this system and ended up buying the Silverback with '60 backboard for $750. I swallowed hard at the price, but concluded that, if you want something of quality that will look nice in your yard, stand solidly, and last more than 5 years, you have to spend this much or more.
Nice goal. Solid. Highly recommended. Be ready to work though. Follow directions and will require a lot of cement, but will be worth it.
My 10 year old son helped me assemble it, but you think it needs two adults to install it.Followed the instructions and spent about 4 to 5 hours to assemble and erect it.Once in the ground and the cement cured, it is sturdy and looks great.
The basketball "system" came well packed and on time. We had it professionally installed and assembled as it had to be set in cement and we anticipated it getting a lot of hard use. It looks great. The kids hang off the rim and it withstands all kinds of "abuse". It is easy to adjust the height of the rim. We would recommend it.
There is a fair amount of shake to the post when the ball hits the backboard. Cement hardens as it ages, and I filled the entire post with cement, so I'm hoping that shake goes away. Also, the backboard and rim aren't as true as higher grade versions; the caroms aren't as precise and the bounce off the rim is distorted because of the post shake.
Really wanted an in-ground option for basketball. Took a few days to setup with the cement drying. Box was missing a few pieces, but called the company and they quickly shipped out the proper piece. Was able to install it with only myself and my wife. I lifted the backboard and she guided the post onto the ground support. Easier than expected once I got the balance down.
Answer: yes
