It was easy to correct grammar when necessary, and then to order a great gift for a member of a wedding party. Nice, simple, and sturdy mug.

Love that I got an Urban Dictionary word definition from someone I know! So much fun and great memory item!! 😊
I like it but it took a long time getting here
Very basic mug but does the trick!
The mug is of good quality but advertisement needs to change as the sample photo for ordering gives the customer an illusion that the entire mug is of that color ordered when it is not

Nice, but I need the “Reservation Dogs” version of “Aho!”
The mug is a gift for our Fantasy Football league winner…or loser. I'm not sure yet; it's a bit of a spoof that will be disclosed on Thanksgiving.
Love it just like your ranking to be noticed at 4 to stabilize with bots at 5 but looks real
