I have 2 of the RTIC coolers and they work great. I bought them a couple of years ago when they got rid of a bunch of inventory when YETI had a lawsuit against them. They were really cheap then. I got a 45 for like $125 and a 65 for $140.
I had a Coleman extreme cooler before too, but in my opinion the RTIC is built way better. I think for occassional use it doesn't matter, but if you use a cooler alot and it gets beat around then it is better to spend the extra money. Of course I would never pay what YETI's are.
WW brought up some good points on how to properly prepare a cooler.
