Not happy at all with this. I bought it thinking with the name “commuter” it would suit me commuting to work every day to keep my sandwiches cool until lunch but that’s not the case. Ive never actually felt it get cool, my typical drive to work is about an hour and it feels nothing at this point, room temp. I rang tech support to check if it was broken an they said it takes 2 hours just to turn on. 2 hours!! Couldn’t believe it and never would have bought it knowing this. The specs on sheet says 2 hours for max coolness so you think it would achieve some sort of coolness before that point but it doesn’t. Its cheaply made, slow and basically a waste of money.
