The Mother Lode TLS Mini 21" is a well-designed bag.  I love the adjustable divider in the main compartment.  The ability to access the front compartment from the outside is really helpful; I put my carry-on "liquids" in the front and it is easily accessible during the security check.  There are two mesh, zip pockets in the main compartment where I put my smaller items (socks, underwear, misc) and it is easy to see and access. The over-all quality of the bag is good; easy to wheel about.  The handle locations allow me (5'2") to easily stow in overhead compartment.  I had no problem with tipping although I did not over-stuff the bag.  I would definitely consider buying the matching larger bag because the organization/pockets were so well-thought out.
