I bought this sack in hopes to try something new that was trending at my school. My gosh. The fun I had was unbelievable. I truly cannot begin to fathom the amount of fun I managed to find within a little ball, a place to play, and multiple friends. I have hacked my sack so many times with so many different friends and my friends have no complaints when it comes to hacking the sack. I gave my girlfriend a hacky sack as a gift and she was so surprised that I gave her something that meant so much to me. To anybody thinking of gifting a loved one something special, I truly recommend giving them a hacky sack. If I had to complain about this, my only complaint would be that it gets dirty depending on the cleanness of your shoes and the area in which you are playing. And I believe that some of the sand inside of the sack found a small hole to crawl through and fall out, which deflated my sack. Other than that I will truly recommend this sack to anybody regardless of their interest in hacky sacking! To those sacking have fun and be safe!
