We have not given out the cups to our volunteers at this time and we have not tried one yet but they seem to be made well and they were delivered quite quickly.

Bought this as a Teacher Appreciation gift for our staff and they absolutely LOVE IT!!!! The fact that it holds both hot and cold beverages and has a straw that you cannot lose sends it over the top! Highly recommend this product.
