Bests & Worsts Reviews from Amazon

I have 5 of these tumblers. I absolutely love them. I used to use Starbucks tumblers but they kept breaking. I was looking for a new one and came across these. I'm so glad I did! They are smaller than the venti sized tumblers but inside hold exactly the same amount (I measured). They keep hot coffee hot for hours and cold coffee with ice cold for hours. I've had ice at the bottom of my cup after 10+ hours. I dont actually use the straws that come with them I had stainless steel straws and they work perfectly with these cups. Would highly recommend these tumblers. I mainly use them for coffee but they work for anything.
