In reply to simondgee: They're just a simple, no frills more budget cam. They're, however, no less dependable; I like them, they just don't feel the same as the more expensive units.
I like them, they're dependable/safe but not so expensive you'd want to cry if you broke/lost one.
They're probably not for everyone, some people go with the more expensive feeling units right from the off.
