At the moment, the only devices that seem to have really cracked the technology are the mega-expensive ones, such as FitBits. The cheapo ones simply aren't at all reliable.
With Apple, Samsung, Fitbit etc you are not just buying the brand. You are paying for the research and development that the cheap manufacturers don't do.
Also those brands have their reputations to maintain. If their product is shoddy, their whole business will collapse.
A £20 watch might look smart but it won't be reliable. I wouldn't even trust the battery in a cheap smartwatch.
