No complaints about the quality of Apple iPods and other mobile phones or tablets. I bought this iPod to give to a person using them for sports. Its small size allows it to hide without suffering any movement. As against the same joke to note about the ridiculous size of the "cable" that no longer deserves the name connector for charging and sync itunes. Personally I still do not like itunes even after a wedding forced more than ten years but I still recognize the brand superiority with apple, more expensive but more reliable with this battery remains reliable despite the weather. An excellent product despite the ridiculous size of the usb cable and classic headset supplied automatically with lovers of good sound always outgrow quickly.
