Review on Extra Thick Exercise Ball For Workout Fitness Balance - Gruper Yoga Ball In 45-75Cm - Anti Burst Yoga Chair For Home And Office With Hand Pump & Workout Guide Access Included by Mike Roberts

I like the durability of this ball. The plastic is thick although the ridges can be uncomfortable if your sitting on it in shorts for any length of time. This ball is a little more costly than what I'm used to. In the past I've paid on average of $7-$9 but I believe it's because the plastic is probably better. Well see, I keep one around to manage my sciatica. Although I use the larger 65 cm ball for this and as an alternative desk chair on occasion. This time I accidentally ordered the 45 cm which is perfect for the intended use of working out at my height but I'm happy enough that I think I'll be using this company again to supply my 65cm ball.
