First and foremost, unlike the model listed for 15.6" laptops, this one actually fits my Lenovo Flex 2 15D 15.6" laptop. Not sure how they rate these things because older laptops had a LOT more case beyond the screen edges... Who knows? But I digress... This discrepency is why I knocked it down to a 4 star rating. Sadly though, Caselogic is FAR from the only laptop case MFG that is guilty of this...The outer cover is your typical black ballistics nylon outer casing with a padded liner, padding while a bit on the thinnish side, is more than ample to protect the laptop from mild thumps and bumps as you go through your day. None of the soft laptop bags I have ever come across are sufficient for protecting against say a hard drop on concrete, but for normal use, this thing is very protective...There are zippers and velcro galonre. The strap clips are plastic, not metal. Good for weight reduction, and not prone to rusting over time. I could claim that plastics fail more often than the pot metal hardware used in some bags, but in all honesty, I have seen metal clips and buckles fail at a much higher rate than the plastic ones. Either way, plastic hardware is typical in this class bag...The storage compartments all appear to be lined with a soft sort of micro fiber ish fleece type material which makes it super easy on things like phone and tablet screens, and all nature of portable device cases. The dedicated pocket for the phone has ample room for my Samsung Galaxy S4, and the front compartment works great for housing the charger, mouse etc... A separate zippered compartment holds plenty of documents. The front and back are padded with a good heavy duty foam insulator to keep bumps and bashes away. And the tablet sleeve is there to allow you to carry your full arsenal of portable tech.You might ask yourself why you would want to carry a laptop, AND a phone, AND a tablet at the same time. Well, in all honesty it can be overkill, but then again, I travel, a LOT with my wife for our business, and we don't yet have a laptop for her. So she tends to swipe the laptop when she needs to get something done. As long as I don't need something PC specific, I can boot up the tablet, and say check on orders, make my blog entries, do client relations communications etc... I love my Galaxy S4 though. I have been known to put my Microsoft Bluetooth keyboard in the tablet pocket to use with the Galaxy on the go! The phone pocket is great for more formal meetings when you don't want the big smartphone lump in your shirt / suit / pants pockets distracting from how sharp dressed you are for your meeting.One part I did not like about it is the incredibly cheap construction and materials of the shoulder strap pad. It seems so incredibly poorly made, and just seems out of place on this laptop bag. Case Logic really should switch to a better made piece for this... I find this to be mostly universally true of laptop cases though, and I suspect only the top end cases have even vaguely adequate shoulder strap pads. If you search Amazon you will find a large selection of add on shoulder strap pads for laptop / messenger bags. Pretty typical problem with all of them! I have the Planet Waves Gel Guitar strap choulder pad, a bit wide, but should work and make this MUCH more secure, and comfortable to boot!My case tends to hold my Lenovo Flex2 15D 15.6" laptop, my Samsung Galaxy S4 in an Otterbox Defender, chargers for both, cable lock for the laptop, mouse, pens, cables, a 10" tablet and its charger, and typically a thick folder or two of letter size documentation for various meetings. With the full load everything is well contained with no funny bumps or protrusions. The strap that holds it to rolling luggage is secure and solid, keeps it well in place. I have at least for testing tossed in my now obsolete Pengpod 1000 10" Linux tablet and charger.The only time I have had it where it had anything that made it odd or lumpy was when carrying an extra pair of external speakers that were somewhat on the largeish side that I was bringing to a client demonstration for a family members business... And even that wasn't too offensive.All in all this is a great laptop case, particularly for the money. Yes it could be better. But in order to get better you are going to likely cough out a couple of hundred bucks, and end up with a high maintenance leather case. I wanted to avoid the cost and maintenance problems associated with leather... Simply put, this case is ideal for my use, and you may find it ideal too. Just don't expect the recommended sizing to be accurate!I wanted to address the issue I have seen on one other users customer photos where the corner seam came undone after a few days. There was no mention in the photo caption if there was any sort of warranty support / return they had, I have had caselogic products in the past and never experienced a sewing failure (although I did have a CD pocket case that had a zipper die after years of abuse...). I would think the zipper failure would be quite uncommon, noisy / squeaky plastic strap hardware is no surprise though, neither would noisy squeaky metal strap hardware. It is the nature of the beast.
