BOSUSport Balance Trainer, Travel Size Allows for Easy Transportation and Storage, 50cm,

It is exactly as described. It is durable and is the right size so that both my son who is five and myself can use it easily. I have had it a few weeks and it has retained the air and it was easy to inflate. I like that it was a little less money than the larger ones, but still can be used in a similar way.

UPDATE: 11/27/15 - The small diameter is not ideal for Pilates. I would recommend the largest for pilates on the Bosu. This small Bosu is better for vertical workouts or very petite individuals. ....Original Review: This is a nice quality Bosu. Works really well for my Intensity Workout and is easy to store and protect from my cats by simply draping my yoga mat over it when not in use. I do, however, need to use a folded up yoga/sticky mat underneat, as it can slide when doing front lunges on a carpet. No fault of the Bosu, just something I learned with certain moves. The sticky mat keeps it nice and secure and safe. The Bosu is very very challenging and takes a few weeks to master in terms of safety and being able to execute moves. My balance has increased to a degree I've never achieved before and I'm pretty stoked about that. I'm also able to do my entire intensity workouts, every move, after only two weeks of being a newbie. This is a smaller Bosu, so if you are tall or have a wide stance, you may want to buy the larger Bosu. I'm 5'6" and struggled a bit with it at first but realized it was because I was so bad at it. Hahah. I'm now able to balance on it and feel its' a good size for me.

Great for balancing routine it’s challenging and fun !

Why did you pick this product vs others?:The included pump didn't work; I went to the hardware store to get a cone shaped air nozzle for my bike air pump. I filled the ball but hear an air leak near the clamp. There's no customer service person to speak with. I bought the brand name so I wouldnt have product issues, but now I wish I had bout a less expensive high rated balance ball. Refund or exchange me?

Gets at core muscles I didn't know I had. Use feels challenging but good. Although the pump is laughably cheap it worked fine for me and I inflated this BOSU very quickly. However poorly designed inflation port and needle make inflation more difficult than necessary, especially because getting the right amount of inflation is a trial-and-error process. Cheap pump but crude connectors are main problem. The booklet that comes with this BOSU has almost no actual info about how to use this, so google and check YouTube for how to use. Simple exercises -- e.g., squats, lunges -- you may already do become a new challenge with new results.Unless your balance and core are already just super, before you start real exercises on this BOSU take some time/sessions to just stand on it, move your body around and get used to it. Music can help a lot. This size (rather than the larger model) is very appropriate for home use and it's just as useful as the larger versions available at the gym. One star off for awkward inflation fittings and cheap pump.

I'm delighted with my Bosu sport ball! I use the larger size at the gym, but I wanted something a little bit smaller for home.See the photos so that you know which equipment to use. First of all, the plug for the ball (to use once you have inflated it) is stapled to a small clear envelope inside a larger clear envelope which contains the instructions.Don't throw out the instructions or you will throw out the plug!The ball was pretty easy to inflate. Yes, the pump is a little cheap, but the issue is that when you have the platform side up, the weight of the platform leaves very little air space inside the ball. So when you start pumping, you have to be very patient. For about a minute you will not seem to be getting any air in the ball at all. All of a sudden, the platform will lift a little bit and it will inflate quickly. I literally inflated it in about two minutes.Once the ball is full and you have the plug handy, slide the pump out and cover the inflation hole in the ball with a finger. With a little bit of timing, you can lift your finger and slide the plug in. Make sure the plug is securely all the way in.I use the ball for ab work because my wrists bother me when trying to do a plank position on the floor. I also have a right shoulder tendon injury. Having my hands on the side of the Bosu ball keeps my wrist in a neutral position and reduces the strain on my shoulder injury.You can do mountain climbers, knee to opposite elbow ab moves and spider climber's (knee to same side elbow) for a great ab worked out. Flip the ball over and you can do crunches.This fall was easy to inflate and thus far I am very happy with it.

Solid quality

Love the colors and is as useful as described online. The pump comes with the product for easy inflating.
