Bests & Worsts Reviews from Amazon

It's totally inadequate. I pressed five, six, eight times and got almost no fizz and also it tastes acidic. I have a feeling that the seltzer and sparkling waters you buy know how to offset the acidity of C02 with the proper balance of alkaline minerals so it tastes good. But the main problem is it's an epic fail and the fizz is barely noticeable no matter how many times you press.
