I'm finding a few issues, but on the whole it's alright for the price.
The main issue seems to be with data updating on a schedule, e.g. email does not download in the background, 3rd party clock and other widgets do not show current values even when set to auto update.
The other thing I've found after the PIN is set during the setup it can't be changed. Going through security - Screen Lock - Security Password - Settings, then selecting PIN actually prompts for a pattern.
