Fatima Zahra (verified owner) –
A few more dings than expected. Bought a “used” grade. It’s structurally sound and watertight, but has a few more cosmetic scratches and dents than the photo suggested. Still fully functional and good value.

Website could be more intuitive. Found what I needed eventually, but the filter system for container types could be better.

Slight price increase from quote to delivery. The initial quote was valid, but by the time I confirmed a week later, the transport costs had gone up slightly due to fuel prices. Understandable, but worth noting.

Wish there were more photos online. The container is fine, but I would have liked to see photos of all four sides and the interior floor before purchasing.

Modification wasn’t perfect. We ordered a container with a added man-door. The door works, but the finish around the weld is a bit rough. It’s on the back so it’s not a huge deal, but for the price of the mod, I expected cleaner work.
