Not impressed with Tumbler

I bought mine (lavender) during the launch, but I just tried it today. I washed every part thoroughly, and put my sip in and was underwhelmed. I had my sip on 3, could taste a little bit, then it went to tasting like plain water. I now have it turned up to 7 and can taste it more. Any tips and tricks from anyone? Do you just have to turn the dial up higher to get the flavor?
