They just are not durable whatsoever. Has a long battery life. The stock feet that come with the mouse are just ok. It?s made breaking in them slightly painful. I had shied away from AirPods as I was really worried about them falling out when running, etc. Its beautifully made, fits well and has a nice unique design. Like I said, great for keys or anything that actually has a keychain, anything else not so much. They are the best, most comfortable and sturdy flip flops Ive ever owned. all my alternatives and value + availability led me here. But these shoes are so comfortable it may become my main pair of running shoes.
