So more expensive than a Dirtworker (got mine for £50) and the only advantage seems to be an extra 1-2litres of water?
Like Mike says, if it's not gonna be much better or cheaper than the established main competitor then it's unlikely to do well.
Also appears to be on wheels which isn't ideal if it's going to be rolling around in the back of a car?
It's a plus that it can be used at home from the mains but i'm sure most mtb riders would have a hose at home which is always going to be easier to use.
Maybe if they market it well and deals appear at under rrp then it could do ok.
And blue is nice, but i'll take yellow any day.
