[EX Q]: It is deceiving in that it did not come with the portable charger and cord as it advertises. We were thoroughly disappointed when the package came and that was missing. The whole point of my 10 year old son wanting the backpack was for that reason. That being said, if you like the backpack the. You will be happy. My son has been in school for 2 months and no damages from the backpack can be sighted.
[EX A]: negative

[EX Q]: So disappointed in this product. It was not as pictured. The picture shows a more square bag. The one I received was more slouchy. I purchased it to use for work for a laptop. Theres no way it would fit. I ended up donating this bag.
[EX A]: negative

[EX Q]: I was very happy to receive the goods. It was very good on the grade. It was especially suitable after installation. The picture was clear, the operation was simple and easy to understand. I didn’t let me down. The last one was not clear. There is no problem with this. Very good, cost-effective is still very high, recommended to buy, all praise service is very thoughtful.
[EX A]:
positive
