Is the LOVEVOOK Carry On Luggage 22x14x9 worth it?

How the expandable zipper on this carry on luggage actually works

Here's the clever bit: this isn't one fixed size, it's two. A second zipper track runs around the shell, and when it's closed, the case sits at the slimmer 40 liter profile most airlines size against. Unzip it and the shell halves pull apart another notch, opening up to 48 liters, about 20% more room, for the days you actually need it. That means you can pack the bag two different ways: tight and legal for the flight there, expanded for the souvenirs and dirty laundry on the way back. The front pocket works on the same logic of separation. It's cut off from the main compartment, sized for a 15.6 inch laptop and an 11 inch tablet, so you unzip one flap at security instead of unpacking the whole case. Inside, a wet/dry separation pocket keeps damp toiletries away from clothes, and compression straps hold everything down so the expanded space doesn't turn into a loose, shifting mess. Four spinner wheels turn independently, so pushing it through a crowded terminal takes a push, not a drag. The polycarbonate hardshell and TSA lock cover the outside; the side hooks just free up your hands at the gate.
