This is a lot of 5 2nd gen 4gb nanos. The 2 on the left work great however the top cap and the on off switch underneath are broken, you can turn them on and off by holding the play pause button down for a second. The other 3 connect to itunes however a couple need to be connected to a cord for power and the scroll wheel on the other doesnt work. There is a 1st gen 2gb nano on the top of the pic that doesnt connect to itunes and finally there is a 6th gen 120gb classic that sometimes connects to itunes and sometimes not. It always shows up as drive f in computer however I cant restore it. Maybe reformatting may help. All are sold as is
