To be totally honest, I had intended to purchase a Christmas Tree Storate Bag at a big box store after the holiday season.  I waited too late and everything was sold out, but I actually came out a winner here!  This bag was better than I could have/would have purchased!  

Pros: Durable,  large enough for a 9' tree with space left over, zippers are strong
Cons: None that I can think of!
