I bought this backpack 3 months ago to replace a briefcase style bag.
I have been very pleased with it. The construction is of sturdy black nylon throughout.
I use the two exterior pockets in the back for small headphones and a paint brush I use for dusting.
The first compartment has pen holders stitched in, so I use it to hold a legal pad holder and other office type things.
The next compartment has two dividers in the bottom third of the bag. One of the dividers is mesh with a zip top, so I use this compartment to hold a cd case, antenna. cords, flash drives and spare disks. This compartment also has a slot to hold an MP3 player and a rubberized hole for a headphone cord.
The final compartment is sized to fit a 17.3 inch laptop. My Dell fits just fine. The bottom of this compartment is thickly padded to absorb shocks to your laptop.
The bag's hardware is all hard plastic like nylon. This initially worried me, but I have had no problems. Each of the three compartments is double zippered.
You can carry it with the handle on the top (I hang mine on a coat rack at work), you can carry it on one shoulder comfortably, or you can wear it as a normal backpack(it has padding against your back.
My only beef with the bag, is that all the compartment subdivisions I mentioned are in the bottom of the bag, so if you are putting in a lot of stuff, the bottom will become over full, while the top still has room to spare. Putting at least some pockets in the to third of the compartments will solve this, and I plan to do this.
Still, I don't see how you could get a better bag for under $30.00. HP did a good job.
This backpack is great for large and small laptops, but keep in mind it is pretty much only for the laptop. It is very slim. Putting in the power brick to my 17in ENVY laptop makes it bulge a bit. But that being said, it is a very classy looking and useful. The design is great. Pockets where you need them and the quality is very good. The cushions on the straps and handle are great. I recommend this backpack if you only carry your laptop and maybe some papers and a mouse.
I purchased this backpack on a whim not knowing if my laptop would be protected. I have a 17.2 inch laptop and with that large screen you do not have alot of support I carry some books, notebooks, my asus transfromer prime and also my laptop and it doesn't ever feel too heavy. The shoulder padding is quite comfortable and give my big laptop plenty of protection. I would recommend this product to anyone with a 17inch or bigger screen!
