Spotlight customer reviews:
Customer Rating: Summary: Great Bag! Comment: I got the 30x50" black version of this bag and it's absolutely huge and works perfectly for what I need. I love that there is a handle built in on both the long and short sides.
I use this to carry a bunch of photography equipment like stands, backdrop cloths, etc... and it does a great job. The only thing that keeps this from getting 5 stars is there is no shoulder strap and/or even D-Rings to add a strap.
