Can someone please help - I have been enjoying using an original iclear 30 tank and I thought it was good but in my local shop I spotted a pro tank and I gave it a whirl and it has been fantastic MUCH more flavour and throat hit and so I picked up yesterday a iclear x.1 and it's the same again it's Absolutely fabulous - have I been ripped off with a duff iclear 30 or are they just not as good as the others ? Thanks in advance for any replies .
