This is better than I expected, it really is a very well made and durable thermos.  I did 2 tests and was completely satisfied.  First I used for my coffee and it kept it hot for many hours.  Next I filled with about 4 ice cubes and tea, it stayed cold all day and even kept the ice ice.  The lid is really well made and easy to put on and take off.  The strap has to purposes, saving the lid and for the D ring.  Your able to clip onto a stroller, belt loop, even a pack back.  The size is great holds a great deal amount, 40 ounces.  Has a large opening for easy filling and pouring.  Comes with instructions for care of your thermos, some do's and don'ts.  This is a 5 star product and recommend this thermos.  Disclosure: I received this product at a discount in exchange for my honest  and unbiased review.  I have no affiliation with this company.
