I purchased the 6 ball set which includes weights of 2, 4, 6, 8, 10, and 12 pounds. Relatively quickly, the 8, 10, and 12 pound medicine balls have each split in half. The lighter balls get very little, if any usage, therefore rendering this set a complete waste of money.
In attempting to contact Cap Barbell I found that their answering machine was not that of a professional company, but a barely audible recording on what sounded like a home voicemail box from 1992, left by a woman with a very unprofessional manner of speaking. Attempts to e-mail the company resulted in similar disappointment. An employee of the company using a generic e-mail address and no identification wrote back a 2 line e-mail filled with spelling, grammar, capitalization, and punctuation mistakes informing me they would not replaced the damaged balls.
Save your money and use it for a product that doesn't break so quickly, and with a company that will help you.
