Bests & Worsts Reviews from Amazon

BEAST Handle for 30oz Tumbler YETI Rambler RTIC and MoreI looked at a bunch of these before settling on this one based on customer reviews. They were right. Quite simply does what it's supposed to do, perfectly. UPDATE 7/23/17: Well, they may advertise a lifetime guarantee, but don't expect them to honor it. Here's a photo of what The Beast will look like in less than a year. It stretches so much it will become unusable, as your cup can just slip through! I contacted customer service on June 29 and I know they read my message -- I can see where the did -- but they never responded. Now I have to waste time with Amazon to get it refunded or force the merchant to honor the replacement guarantee it advertises. Very disappointing!!!
