This cooler box is really sturdy and quality is excellent. The biggest and the most important thing is that it solves the purpose for which it has been made. .

Until two days, it keeps things chilled and on the third day also the things are cold (water, cold drinks, etc.). It is a great thing to have during travel especially from water perspective so that you don't have to buy water enroute again and again or have unhygienic water. We deep froze some water bottles overnight before our journey and could still find ice in some until two days and those remained really cold on third day as well. 

This can be used to store chilled and/or deep frozen things and can very easily keep them intact for 3 days and may be longer if you also put ice in the box itself.

This cooler box comes in 4 sizes and each size has a maximum hours rate at which drinks are chilled although the hours could be exceeded. the sizes available now are 34.5liters,25liters,10liters and 4.5liters. please choose the most appropriate size for your needs. The cooler box is green in color  and the covers are grey.
