Review title is mostly satisfied - has common design flaws [SEP] this is not the 'model' I received.  I received the version with 1 large compartment on the front (as opposed to the pictured 2 compartments).  I was packing for a job, and wanted to use right away so I did not contact seller to see about an exchange.<br /><br />as usual, whoever makes stylist's bags does not seem to test the spaces with actual tools inside, fully loaded - as most stylist would use it.  the right side has a heat resistant pocket for hot tools.  it fits my flat iron & a standard length curling iron (mine must be long as it sticks out the top).  difficult to use with tools still hot as the cords really have no space other than inside this pocket.  there are envelope slots in the 'door' of this compartment.  I have tried to fit a brush ... but it quickly becomes too bulky and difficult to zipper shut.<br /><br />I use zucca cases inside the main compartment which work fine.  I specifically ordered this because it was soft-sided ... but that means when fully loaded, it collapses easily and I really watch how I set it up.  also, as I am using it with zucca bags (as opposed to the boxes shown) - getting into just one bag at a time is difficult since they rely on being stacked just so.  my zucca bags do not protrude out of the compartment, but fit snuggly in which, again, becomes a problem when using the pockets & accompanying bags that are in this front 'door'.  I usually have to lay the bag back to get it zipped close (like the 80's - laying on the bed to zipper your pants!! C-:  )<br /><br />it seems sturdy enough; the proportions of the backpack aspect are good and I really like the heavy duty top handle.  time will tell ... my zucca case started coming apart at the seams after just 1 year.  hoping this one is better reinforced
