Reviews

You could buy a dozen of these cases for the price of the most expensive one in our test. It performed as well as those more expensive “branded” cases in our lift and drop and puncture resistance tests. It leaked a bit of water, but no more than most other models. We thought it was easy to use and had a very comfortable handle, but it’s not ultra-light at 2.7kg. It meets Air New Zealand carry-on baggage rules only. Great value.

Our tests

Stability
We loaded the bags with 4kg of clothing and checked how far they could tilt without falling over.

Rain
Whether it’s when wheeling your bag to the airport, or finding the bag trolley was left out on the runway in the rain, some level of water resistance is useful. We put bags lined with dry newsprint paper upright under a shower rig for 10 minutes to assess their water resistance.

Puncture
To test resistance to sharp objects, our rig dropped a metal cone onto the case and we measured the diameter of the resulting puncture mark.

Lift and drop
Our rig snatches the bag up (testing the handle) and drops it from a height of 900mm onto its base and wheels. We repeat this 300 times or until it fails, whichever comes first. Bags that survive the drop test are tested for 30 minutes on a rolling rig to check the wheels still work.

Ease of use
Three testers take the bags loaded with 4kg for a stroll. They move in and out of an elevator, down stairs and through a doorway. They drag the bags across carpet, a cement path and asphalt. They consider handle comfort and length, noise, and overall stability in two-wheel and four-wheel use (if applicable).
