I have purchased many, many RTIC products. I am ,well, aware how they're supposed to be used.
This is the very FIRST time I have an issue, or complaint.
I purchased the pretty , purple ish, color after I owned a 30 oz tumbler already, recently also.
There has to be some sort of Factory Defect with the Periwinkle, or the batch or something. I use this cup in the same way, always.
Long story short, the ICE DID NOT last hardly at all. I may as well have used a Solo cup. Yes, it was bad.
I actually did call to inquire about sending it back. I'm NOT a complainer but it really was a surprising disappointment this time.
I ordered the same as my previous one that I had no problem with. It arrived today. I'm sure it will be fine.
The only thing that bothers me is that it's Not Purple. I was weary of the periwinkle so stayed away.
The plum is LOVELY but maybe next time.
I hope someone actually reads this.
Thank you for asking.
I added a pic of my Cabinet FULL of RTIC.
