Purchased this as I spend a lot of time on the road and don't always have the time to sit and finish a drink so end up taking it with me and then it goes cold and gets binned so too much waste and getting costly... this item has been a god send in keeping the drinks warm for as long as i need them to be .. there are 2 intensity levels and I prefer to use the higher one... drinks def do stay hot and I'm super impressed... fits in my cup holder perfectly... my fella was so impressed he wanted one, tho his was to keep drinks cold... he too found it worked a treat however it didn't fit in his cup holder but a simple improvisation soon fixed that...
both really pleased with the item.. shame it plugs into a car cigarette lighter and not by usb as could be used in the office too
