This is a great wheeled backpack design. Can hold up to a 17" laptop. I regularly travel with a 17" laptop and a tablet. I've been traveling with this back pack all over the world for about 10 months now. It can hold a lot of gear, fits in almost all airline overhead bins and converts from wheeled to backpack mode in seconds. The single telescoping handle never gets stuck.
It just has a couple design flaws.
1.) The plastic stand on the bottom of the bag broke after 4 months.
2.) The plastic supports inside the bottom of the bag are to thin and bend to easily. Causing the bag to Topple over randomly while standing.
I fixed the above to issues by removing the plastic support brace, replacing it with stylish bronze drawer handles bolted through the plastic support under the bottom cushion of the bag and cutting a thin piece of plexi glass to size and inserting under the bottom cushioning inside the bag. Now no more toppling over issues.
