I purchased 10 of the 65cm stability balls for my workout facility. I am thoroughly impressed with the customer service of this company, the quality of products, and the reasonable pricing. Prior to purchasing these balls from Black Mountain Products, I purchased 55cm stability balls from another company/brand a year ago, at a price which was about 2.5 times the amount (had I known the difference in price at that time I would have saved myself a lot of $$ money and, as explained next, frustration over many of the product features of the other brand). When comparing the two products, I highly recommend the Black Mountain stability balls over the other brand of stability balls. First, the stability balls of Black Mountain are easy to inflate, especially since a hand-pump was included with each ball. My experience of inflating the OTHER brand’s stability balls was a long, inefficient process: 1 – unfold, 2 – wait 24 hours for the material to acclimate to proper room temperature, 3 – pump up to 75% capacity using an air compressor, 4 – wait another 24 hours of the material to acclimate, 5 – finish inflating to 100% capacity. On the contrary, the Black Mountain balls were able to be inflated within minutes of removal from the package. And, the hand-pump is very convenient! We had all 10 balls inflated by the end of the day and available for use at our facility. So, in addition to the friendly customer service, another great first-impression was made as we prepared the product for use! �� On the workout floor we have been pleased with the quality of these stability balls. When compared to the material of the other brand, the Black Mount stability ball has a non-slippery texture. In addition, the surface is relatively smooth whereas the other brand’s stability balls have very rigid grip lines, which are uncomfortable during use and leave pressure point marks on the skin after extended contact with the ball during an exercise movement. So, in addition to the non-slip material, the Black Mountain stability ball is much preferred by our customers for comfort. I highly recommend this company and this product (and I should also note here that I am a huge fan of Black Mountain’s resistance bands!).
