Review on Bamboo Double Wall Borosilicate Coffee Tea Cup by Wagner Witlin

Over the course of about 3 years I have bought four different types of these double-walled glass coffee cups. When I live alone I make coffee one cup at a time and prefer a 10-12 ounce large and want it to stay hot for as long as possible. That's my top priority. Second is durability. This is by far the best I've ever had. This is a heavier glass and wooden top with a plastic edge seal instead of single wall glass. It doesn't rattle, sweat or generate heat like others I've bought. In addition, it is very durable. The rest was much more fragile. The best of them crashed twice. Once when the handle caused a crack that shattered the entire mug, and another when my dog knocked it off the armrest of my chair and onto the carpet. Another had a broken lid when it arrived despite careful packaging. In short, it has all the features I want and at a lower price than the previous best. It feels thicker with more dead space between the walls because it also retains heat for longer! However, that means it's not really a 16-ounce mug. In practice, it's not even 12 ounces. 10 is the safest amount when using a lid.
