The GIVEMIFIVE Running Armband is a must-have for anyone who loves to exercise and listen to music at THE same time .Based on my observations, this product is made of high-quality materials that protect my electronics from water and sweat, and it fits perfectly on my arm. The adjustable strap ensures that it won't slip while I`m running. The only downside is that it can be a bit bulky, but that's a small price to pay for full protection. Overall, I'm extremely happy with my purchase..
