Stainless does not keep ice where as my red one does

I have purchased 3 of these. I bought a red one for myself & loved it so much that I ordered a stainless one for my Father my husband asked where his was so I ordered him a stainless one. My red one keeps things very cold & holds ice nicely all day! My Dad lives in another city so I don’t have 1st hand knowledge of his. My husband really didn’t use his so recently I have started using it some while mine is being washed. His stainless does not hold ice & the outside has condensation. It’s too late to return thru Amazon so I’m hoping that the manufacturer of COLD 1 will reach out to me so that I can exchange this.
