50 good We bought 2 of these because the description said it would be okay outside. 

One of them held up fine (3 months, no extreme cold or heat. Im writing this in May). The other looks like the top is going to pop off it is bowing up so badly (see pic). Its unusable. 

Love the look of these, but extremely disappointed that the quality is so poor on one of them. We now need to buy this again or find 2 other options.
