yeti "colster" koozie
 

This was my first yeti purchase, and I will say it does an amazing job! Get side tracked and leave your beer behind. ...no worries. ...still cold. Hot sunny days is where it shines the most.

The only issue I have, is the first sip always gives a weird taste. It's almost like the taste you get when you stick your tongue on a 9v battery, but more faint. Is there a charge being produced when it is slid into the colster? Anyone else notice this.

Whiskey solves that problem.......

I have a buddy who has one, he used it all summer and I never heard him say or complain about it. But his drink would stay cold for hours.

I unscrew the lid and replace the can. Never had the issue you are describing

Love mine. Best $30 I've ever spent. Don't have the taste issue though, that's weird

I'm sure they work but Yeti is the latest fad. I always say if a beer gets warm before you can finish it without a coozie you're not drinking fast enough so why bother.

Dissimilar metals, your tongue may be passing current.

I just bought one last weekend. It works incredibly well.

Maybe you have a bad ground. Go n the bathroom and check your Zincs.

They make a mug that a friend uses for his cocktails. There was still ice in it 2 days later when I was cleaning up the bar in the shop. Since he cant remember where he left it, it may well become the property of the bar! :drink:
