If you like the way this bag looks in the photos form the seller, I think you'l like the bag overall. The price is very fair for the quality and design. It's from a brand I have recently gotten a few other items from and feel like it's trustworthy in terms of the quality and value within a reasonable budget.

A few things to note:
The strap is not padded. Not a problem for me, as the bag size means I won't be loading it up to make it really heavy, but if bothers you, an extra strap or a strap pad may be desirable. Personally, I'd rather keep it minimal and lean for a bag of this size and save the padded straps for heavier loads.
The front flap closures are with buttons, which is much faster and less hassle that undoing and redoing buckles. The buckles are just for adjusting the length of the closure strap.
The flap folds over the bag, but it does leave a little room for the smallest items to fall out if the bag is upside down, and also bugs could get in. Probably not a problem for most people most of the time, but not a bag I would choose for a camping trip in the forest. The rain cover which is included and can be stashed in one of the zippered pockets can help.
