It has been about 7 hours in my real-world listening usage. This stand is incredible! I tried more expensive and famous options and they were tight. My bike will not fall over, even when someone really bumps into it hard. 3 stars now because it bigger and flops off my feet but the strap on top still squeeze me and i have narrow feet. This lock works perfectly and takes the guesswork out of trailer theft. This product does not compare to the original which I currently have in maroon. They started falling apart immediately. They fit her ears well and she was extremely happy with the sound quality. The coil in the wireless station is too low to allow the phone to stand on end.
