i've got one, best hot/cold cup that i've used. hot beverage is all ways hot, hour trip out of town, leave cup in truck at least an hour, still hot on ride home.
i brewed up a coffee this morning about 10:00 went skating at noon, left it in truck for about an hour, drove out of town, came home at about 4:00, coffee still warn, not hot, but not cold either, still very drinkable.
not sure of the price, i got mine from a service company.
never tried it on cold drinks, but grandkids have them, ice stays most of an 18 hole golf game. they're good.
