SPRIBalance Trainer Dome Shape Half-Exercise Ball with Non-Skid Base – Pro (65cm) or Sport (50cm) for Balance Training, Strength Building, Toning, and Improved Flexibility

Unfortunately after mine was delivered, I found a problem with inflating it. The place where you stick the tube into was loose and would not hold. The mfg employee was great by offering to replace it, Amazon offered to replace it also. I decided to keep using the same equipment at the gym. If I was younger I probably would have gotten another for my house. The gadget is well made and when I use it I can feel every muscle in my legs working to get stronger. I highly recommend the product !

Very well made. Sturdy. Holds air well. Great price.

I wanted one like at the gym. This is much smaller. My fault for not measuring. Ok quality but not what I expected

I use a different brand at the gym for balance, I have neuropathy in my feet. I noticed the SPRI brand on sale on Black Friday. I ordered it and it's great. Came supper fast and I had no problem blowing it up. I've used it every day since. I bought the larger one. So glad I did. Thank you so much.

If you’ve ever used a large bosu, this is a smaller size but just as sturdy. I use it to practice balance and also for crunches. It works well for me. I’m 5’ 8” and 160 lbs.

So far---so good. You can see and feel the quality in the SPRI Balance Trainer. We tried another competitors balance trainer and had to return it because it would lose air each time you would stand on that product. We are looking forward to all the health benefits the SPRI provides.

So many things to do with this, and great quality!

When filled, leaks around the plug if even a few pounds of pressure are applied. I see no way to remedy this - I've used the end of a walking stick & rested all my weight on it to try to force the plug in farther, no go. Don't buy it. Returned for refund.

Really good product. Sturdy, professional grade. Just about 3 or 4 cm smaller than a typical fitness club version. But for home, completely okay.
