I liked how fast the charge was They definitely dont whistle. However, this is marred by a constant background hiss on any input. However, after 3 months off and on use, the seam along the top of the foot has started splitting. Great for hanging hats jackets purses whatever. which I would have been upset about but surprisingly I wasnt when I opened the first spice wrack to find 3 broken containers. Not as sturdy as i thought it would be but it does the job just fine. it’s comes with the case, a cute clip on keychain, wires to attach to the airpods so you don’t loose them & a cleaning brush! The bikes are super secure and there is never metal with metal contact. Will update after some wear and tear!
