Query: Perrier price for so so water

I have little use for kitchen gadgets that you have to read the manual every time you use it. Shake 5 times, make sure you screw it on straight, don't forget both tubes, only fill to the line, now go find the black cartridge holder, screw it in, bang!!!!, what the hell happened, oh crap I forgot the little tube thing, dang now the gasket is screwed up. I suppose it is nice if you are going to entertain and you want to impress but again, you'll need to spend a good 15 minutes trying to figure the damn thing out and if you don't use cold water, you'll get bad water out. Why not buy perrier or pellegrino? After you calculate the cost with the very expensive CO2 charges, it's much cheaper to buy the good stuff.
