One reviewer shared, "Really ergonomic, keeps coffee warm but doesn't burn your hand. It's light, easy to use and doesn't taste like horrid plastic. It's an exact Medium size, perfect for a range of different coffee shops and also for a home percolator. I thought the lid might be unreliable but it's tight and doesn't leak around the seal ..."

Another shared, "This cup has been a great substitute for all the to-go cups I'd have otherwise used. It travels well and I like the look of it. Plus, I can always tell if it's clean or dirty."
