I've tried two of these speaker docks, and both had lousy lightning connectors. The male connector on the dock had a loose fit, so the device did not work when docked. However, a lightning-USB cord, which fit into the iPod Touch 5 snugly, worked well.
I had a JBL speaker dock for my iPhone 3/4 and was really please with it, which is why I went for this one, but the iPhone 5 version with lightning connector does not do the job it is designed for.
Clearly I am not intending to remove the case or bumper from my iPhone every time I want to listen to music or charge my phone, which is the only way you can get it to fit! I wanted to give this product no stars, but this system wouldn't let me do that, so it got a reluctant 1.
This product is not fit for purpose and needs an urgent upgrade.
