It came with only ONE ball and NO adjustment parts to raise the hoop height. NOTHING in the description said it would not have all of the PARTS !

The base of the chair is fine, but the ball that came with it was no where near fitting into the base. It was very small and falls onto the floor. I used my own 65cm ball in place of the ball that came with the base. It also didn't come with the little metal bars that are shown on the side to hold the ball in place.

Despite what is stated in the Q&A section of this page, this ball does not come with a pump or even any instructions. During post-purchase contact with the seller, they verified that there was no pump.

Attached is a picture of everything I received. The quality of the ball seemed OK enough (although obviously I never inflated the ball). The material felt thick enough that the ball would hold up to normal use. And due to the lack of included instructions, I was unclear if I even had all the parts, but it looks like the product does not comes with an adapter so that a bike pump can be used to inflate it. This was a major negative for me.

While the price is right, the lack of pump, any kind of instructions, and bicycle pump adapter makes this a no go for me. I'm returning today.

Missing a ball and only received one piercing rod

I purchased the MAC-T safe soccer balls for a middle school physical education program and overall I am very dissatisfied. At the end of the first day one of the balls was already deformed in shape, and it was NOT due to over-inflating. I thought it would just be the one soccer ball I had issues with. However, over time only one out of the six is not deformed. Only positive is that they were extremely safe and definitely prevented possible injuries on more than one occasion.

I had been very excited about receiving these in the mail, but was very disappointed to find that it only came with one. I originally justified spending $30 on it because I thought it was a set of two and how convenient it would be to have something I  could leave on my shoes in between super sets. If I had known it was not a set I wouldn't have paid $30 and would have found something that was better priced. I'll probably send it back and find something else.

I would love this product except it only comes with one motorized part so you can only build one toy at a time. My two year old want to build them all and didn't understand you had to take one apart to build another. It lost his interest.

Decent ball for the price. My package arrived containing the deflated ball, a plastic pump, two valve stoppers, and a mini-fork to lift the valve stoppers.

The ball has a stripe of images for ball exercises, which I found helpful. However, I usually just YouTube the workout exercises I need.

1 piece was missing in this toy and I noticed once open and with box in trash, nothing I could do.

and it lasted the whole one day! My son tore on piece completely and got really upset. I ordered another one, and the exact same thing happened within hours. Somehow one piece is molded differently from the whole ball and looks like it was glued to it. So it comes apart from the ball when pulled.

It arrive in one piece, but the quality of it's make could use improvement. Two of the teeth on one of the covers were flawed and unstable. This also caused the cover to jut out just enough to hinder the ball's movement. Disappointing, but I managed to glue it on and put an end to that issue.

This actually only comes with ONE bar, the one with the side handles on both side. The pictures and wording for this is very misleading! Why would you show 8 different cable attachments and in the description lat bar and accessories if it only comes with one part... In the process of returning it...

This is ONE ball..don't think it is packaged in three like the picture. Overpriced for one.

It loosened after I first installed it, I tried to make it tighter and it just snapped in two.  It is designed to install a ball on top, but the bolt on the bottom just isn't large enough in my opinion to get the item tight enough, and the the bolt is captive and cant be replaced once it broke.  Bummer, I really wanted this too

Picture showed it came with an adjuster as well...wasn't in package, so not sure if it was supposed to be included.  Product is in good shape.

The description of this item clearly states that it is a set of 12 stress balls ("2.5 inch balls in assorted neon colors, 1 dz per order"), so I assumed that the other reviews were based on a prior version of the product.  However, I received only 1 ball.  First, $6 is way too much for a single stress ball, and second, it is false advertising to state that a customer is purchasing 12 balls but then to send only 1!  I will be returning this product and requesting a full refund.

There was only one screw in the package.  I had to go out to buy 6 more screws.
