These are great cups. They stay cold for a full day and a half as advertised. Also the vendor was very helpful and worked with me to get the logo that I wanted.
Supplier’s representative has been very responsive and ready to help during entire process of sample delivery. Unfortunately, two of the four samples had defects which normally you wouldn’t expect for a sample. However supplier assured that they will take care of such deficiencies in future so I still decided to go along with them.
