Very good

Great little kit, though as previously mentioned, one or two minor fit issues where the bits or the extension are not tight. Not a big issue though.
The box is VERY securely close with a plastic clip and an additional metal snap. All the bits stand up together at the press of a spring loaded button to make them all accessible, very neat. The handle is quite tight to get out of its holder though!
A fantastic range of tiny driver bits suitable for all small electronic applications. I completely stripped an iPhone 4S down with this kit (needed a separate spudger though of course).
