Remember this?  We used it for our trip from LA to SF this past weekend.  I used 1 blue ice and 1 long ice snake to keep all the items inside cool during our trip.  We had 4 yogurts, 3 bottles of milk and some fruits (grapes and persimmon).  All these were for my son as he needed 1 time milk (the rest for the arrival at SF) and yogurt as snack during the trip. 

This insulated lunch tote can keep the stuff cold and still cold when we arrived in SF after a long 8 hours total trip.  My blue ice was still somewhat frozen, but the ice snake was in liquid stage.  We had a mini refrigerator in the hotel room and I stored these into the freezer.

Overall, I would give it a 5/5 rating.  It is stylish and yet able to do the job well.  No complain.
