In my late 70's and picking up heavy boxes can be a risk to my back or balance. This includes heavy box deliveries and/or moving boxes around the house. Quick simple solution at reasonable price.
Pros
Sturdy enough to handle rough terrain
Cons
May not be able to handle repeated or frequent use on a daily basis
Purchased to haul larger grocery stock from front to rear of an old brick "shotgun house". I''d prefer a unit with (slightly larger) flat-free rubber tires and slightly stronger build. FWIW it does save me in some some grief and pain. not much of a time saver but I use it. Arrives pre-assembled and at price point. I have zero complaints. I would pay up for a stronger model of similar size and function for a few more bucks. Bottom line, it''s worth $35 as is but no more. It does work as advertised and a little beyond.
