You think that fools and their money aren't easily parted?
Not often you see somebody who decides to stand up for fools.... lol
As long as it does what it says it does, it's of good quality and that's what the purchaser wants, or if they think it might make a nice present, then that person is hardly a fool. However, if they expect to be buying something like a Grainfather for the £75 or whatever it is this particular machine costs, then yes, they'd be a fool.
Don't forget we have hundreds of years experience between us and we can spot the over-priced, the fad and the lame duck and know that for a few hours work and less money than the cost of one of those units we can be brewing all grain beer.
I wouldn't mind betting many people here own kitchen gadgets such as soup makers, toasted sandwich makers, smoothie makers and the like. All arguably pointless if you have a kitchen with pans and a blender.
Hopefully, at least some of those people might find a forum like this if they want to find out more about brewing at home. Maybe they did buy it under some illusion and are 'fools' but if it leads them here and it becomes a hobby they enjoy and become really proficient at, who cares?
Much like when the occasional person signs up to a forum, asks for a clone recipe for Carling or Fosters and gets sneered and laughed at and disappears never to even start brewing. Rather than telling them it's a crap beer, we should be telling them that it's an extremely difficult beer to brew at home, but if they like that style of beer, here's something they can brew at home and they might like, they might give it a go and become more adventurous in their beer drinking.
