What are you using now? I received 2 iClears with different purchases, tried them and threw them in the trash.
We all have different tastes and needs though, so that isn't a bash on the iClears, just how I felt about them. See how it is all subjective? Plenty of people love them. For example I have 2 pt's and 4 pt2 minis's and haven't had any of them leak, and I carry them lose in my front pocket all day, no issues. Yet I have read many posts about leaking, gurgling etc.... My experience doesnt mean these other tanks aren't leaking and having issues though. It is all relative.
So, what are you using now might be a better place to start
