This product is really great. I haven't had any problems with the wheels or any of the zippers. The material is durable. I would have given this a solid 5 star rating, but it doesn't have the padding some of the higher priced briefcases have to protect laptops. I don't travel that much with mine, so it should be fine, plus I have a laptop sleeve that will give extra protection when traveling. If you are not careful, you could possibly damage a laptop when traveling with this bag. It also has enough compartments to hold all of your personal items so that is a great plus. This is a GREAT value and a great buy. I recommend it.
