RTIC vs YETI cup

Ok long post probably. Last year on here and face book lots of discussion on this new company and their coolers. Coolers about half price of Yeti and others. Complaints it was taking forever to get coolers. Well the other day I saw a post on face book about their cups. I go in search off and found a bunch of reviews on their cups. And being the money saving WannaB kinda guy I am I checked them out. 30 oz yeti 40.00 and sold over the holidays for 80.00. So the RTIC 30 oz is 19.95 plus shipping. My daughter had bought me the 20 oz yeti for my birthday and I like it so I decided to get her one and my wife one. When I placed the order it came up free shipping. Good deal. So only draw back if it is one, it took over 3 wks to get in, there again not a big deal to me. Came yesterday so I decided to do my own test. Filled up my 20 oz with crushed ice, dumped it into the 30 oz then filled the 20 oz up again. Put on lids and sat them on the counter. Temp in house roughly 68 constant. It has now been 26 hrs and they both have the same amount of ice and water in them. They still have roughly a coffee cup of ice left. So in conclusion from my un scientific study the RTIC is just as good as the YETI at half the price.
The only thing is they only offer the 30 oz not a 20. But for another 4 plus change they have a no spill cap.
