Trideer Exercise Ball for Yoga, Pilates & Fitness – Stability Ball Equipment for Home Gym & Office Chair, Core & Balance Training Accessories, Physical Therapy Equipment, Quick Pump Included, 5 Sizes

Sturdy, versatile, and great quality
This exercise ball is excellent! It’s very sturdy and holds air well without slowly deflating. The size is perfect and provides great support for workouts, stretching, and even sitting at a desk. The material feels thick and durable, and it was easy to inflate. Great value for the price — I use it regularly and would definitely recommend it.

Decent Ball
Easy to inflate. It does what I need it to do, however, it does not hold air very well. I have to pump it back up at least once a week.

Awesome Ball for Dogs
Over the years, I have purchased quite a few different yoga balls for my Boston Terriers to play with. The Trideer Extra Thick exercise ball is by FAR the most durable. My pups cannot contain themselves when this ball comes out of the garage. We have an air compressor so filling it is quite easy and the pin stays in place despite my dogs constantly attempting to pull it out. Holds air well and the thickness of the rubber holds up to months of wear and tear. Great product!

Perfect.
I injured my back in November. I used up my allotted appointments for P/T and want to keep up my exercises. This exercise ball is fine. I am not crazy about the pump. There must be a better way short of buying an electric pump.

great item bought for my son to use at his pc whilst gaming to help him develop his core muscles. brilliant perfect size and strong!

This product is nicely designed. It has a stylish deer graphic logo on it, which adds to its cachet. Right out of the box, you are greeted with a very effective easy-to-use foot-pump, that absolutely minimizes the hassle of inflation that typical hand pumps would offer – this unit with the included foot pump was the easiest time I ever had inflating a Swiss Ball. I believe this product is designed to the minimum thickness standards to give it a “heavy duty” or “puncture-resistant” designation, but I will stress that these units will all likely fail if used in the presence of even a small chip of glass left on the floor from a broken wine glass or light bulb! I think a manufacturer would have to go up to a material like Kevlar for one of these Swiss Balls to be relatively puncture-proof, and I doubt they have created a Kevlar that can expand like this rubber can, nor would it be cost-efficient. So a word of warning – if you or your housemates are prone to breaking the occasional glass item and fail to completely vacuum or sweep up every little shard of glass, be prepared to order a new one of these, for this is what will bring you back down to Earth in an instant if you happen to place your new Swiss Ball on top of any small particle of glass and apply downward pressure (I bought this unit for a buddy who did just that – popped his previous Swiss Ball – and I found a few shards of glass around his work area afterwards, where he uses the Swiss Ball as a chair!). Also, I was unaware of this, but if you do manage to burst this product through the above-mentioned housekeeping negligence, especially if you are in the middle of doing flys or presses with dumbbells etc., there is a real possibility of doing injury to yourself if you experience a sudden bursting. And, again, I stress, this (bursting) is likely only to occur if any sharp item such as a small piece of broken glass, a stray sharp-pointed screw, etc., is left lurking on the floor proximal to your area of use. Otherwise, if you keep this unit stored out of direct sunlight and away from anything that could puncture it, it should last you many years.
