At just over $4 each, it is pretty inexpensive. This week at Walgreens I can get similar, inexpensive backpacks on sale for $3 (wow! - but only in late July or August).
PROS:
Price (try to time your purchase when it is priced $85)
Selection of colors, varied but not stigmatizing for school kids.
All zippers worked (see Cons about the engineering of the zippers)
A mesh water bottle side pocket is versatile.
Bungee cord on front looks useful for carrying the odd "thing."  Not sure what-- Maybe a sweater on a multi-season day of school?
It is easier to get 24 backpacks delivered by UPS, than wiping out the Walgreens display in August and lugging them home.
CONS:
The front zipper pocket is poorly designed. The first 1 or 8 times I opened the front pocket zipper, it felt as if it were caught on  something and was breaking/tearing. It is the seam that binds it initially. It loosens up after some use.
Few frills or extra pockets or extra carrying space.
The front pocket adds no additional girth-- as in, anything put into it, reduces the space in the main compartment.
The inside wall of the front pocket is made of a thin, polyester lining material.
No additional padding in the back of the main compartment.

I got these for the church school supply give-away at our food pantry. I ended up needing to talk to the seller and that was a bad experience that finally turned very good in the end. Because I couldn't stop their shipment in time, I ended up with 15 more backpacks than I needed, But that meant that I was able to give them the next day to a sudden community effort to assemble items for the ReUnification of 250 or more the ICE-separated families in New Mexico this week,
