Question: How easy is to adjust the height ? Can a 7 year old do it on his own? Thanks!
Document: Finally ordered it after sitting on my wish list for about a year. About as heavy duty as you can get for a water filled tank backboard. Nice adjust ability. 7 1/2' to 10' works well for me and the kids.Delivery company did a good job as it's a little big for the normal UPS truck. They arranged an appointment to drop it off.It was missing one(1) required bolt (one bag of hardware had broken open), otherwise it was well packaged.
It is not &#34;The Beast,&#34; which Spalding also sells, but it is quite awesome nonetheless. For the price, it better be, right?Plenty sturdy when filled with water.Mostly sturdy upon ball impact. Of course, nothing beats in-ground, but this is quite good.Like the built-in ball return connected from base to pole. Works.LOVE the height adjustment mechanism.13-year-old son and dad successfully put it together.
Very stable system, the ball bounces/rebounds great off the acrylic backboard. Very easy to adjust the height. No need to spend an extra $500 on the Beast model (glass backboard) unless you have extra cash lying around and you don't have to worry about the potential to crack or shatter the glass after a thunderous dunk. Easy to install in 2 hours.
Best home basketball court ever, wish I had this as a kid but my 4-year-old upcoming star really loves it.
Very solid hoop. Big & sturdy. The design has the hoop quite far forward from the base, so just know what you're getting into for that. Assembled mostly myself with my 13 & 11 year old sons on hand for a few steps. Instructions pretty clear, found it useful to lay out all the nuts & bolts beforehand.My boys love the hoop, and the incrementally adjustable rim is a great feature.
As other reviews have pointed out there are a few spots in the instructions that can be a bit perplexing (the instruction book is one written for multiple goals that are similar, but not all the same). Take your time and look at the diagrams, read the steps over, and carefully analyze what parts your goal has and you'll be fine. I was able to assemble this goal by myself in my garage. I used a bar-height old chair and some styrofoam blocks in place of a saw horse.
For 90 percent of the set up I did alone. My 12 yr old son help hold certain pieces in place while we secured them to the structure. You will need two adults to move into place after loading the base with sand or water. We are extremely happy with the hoop. Easy to lower and raise.
I found the assembly directions easy to follow and had the goal together and up in about 2 hours. After assembling the unit I found it to be relativly solid with and acceptable amount of pole movement for a portable goal. My girls adjust the hoop with ease and have enjoyed using every day since we got it. I used a few extra ground anchors to assure with the larger backboard it would stay put. I am very pleased with the purchase so far.
It took a whole day it seemed like to get it put together with my neighbor putting it together was not easy instructions are not that great at all. But the finished product is wonderful. I bought this I have 4 boys 11, 9, 7 and 2 so it will get much use. I didn't want to buy something really cheap that I would have to re-buy again this hoop fit my needs. I wished I could have got The Beast but this one is perfect.
Great system. Very good quality for the money. Assembly took about 2 1/2 hours but went fairly smooth. The height adjustment works very well and the system feels very sturdy. Easy enough to move if needed. Would definitely recommend.
