My company gave a few of these away as a prize. I was lucky enough to get one. That was 10 years ago and I have been a very pleased customer ever since. I jave fallen on concrete stairs and used this cup to brace my fall. A huge feat in the side of the cup..still seals like it was new. I have purchased about 10 more since I was first introduced and it just keeps getting better every year. I was awarded a yeti cup as another prize at work this year. I tried it a few times but I does not come close to my west loop. That yeti is bow a pen holder. These coffee mugs are the best for hot or cold. Won't matter. Thank you contigo for making a quality product and having top notch customer service if needed.  Customer for life.
