Clara Becker (verified owner) –
Minor rust spot on the roof. Not a big deal for a used container, and it was sealed easily. Just something to check upon delivery.

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.
Oscar Diaz (verified owner) –
Excellent condition. “Like new” is an understatement. This 20ft container looked like it had never been used. Fantastic value.

Maxwell Stone (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.
Rhys Williams (verified owner) –
Website could be more intuitive. Found what I needed eventually, but the filter system for container types could be better.

Bought for a disaster relief organization. Colli Trans worked with us on pricing and delivered quickly to a crisis area. Thank you for your compassion.
Kofi Mensah (verified owner) –
Grade was a bit optimistic. I paid for a “wind and watertight” grade, but the floor has a few more worn spots than I expected. It’s still functional for my storage needs, but I feel I slightly overpaid for the condition.
Elara Whitlock (verified owner) –
Sold my old container to them! Didn’t know they bought used containers too. Got a fair price and upgraded to a larger one.

Average experience. The container is as described. The service was okay. Nothing terrible, nothing amazing. It met the basic requirement.
Florence Church (verified owner) –
Disappointed with condition. Advertised as “good condition,” but it arrived with significant rust on the underside and a noticeable dent on one side that wasn’t in the listing photos. It’s still usable for my low-priority storage, but I feel misled.
Rhys Williams (verified owner) –
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.
Selena Vega (verified owner) –
Customer for life. After this experience, I won’t go anywhere else.

Damage on delivery. The container was dropped during placement, causing a bend in the door frame that now makes it difficult to seal properly. It’s been two weeks and I’m still waiting on a resolution from their claims department. Very frustrating.
Greta Weber (verified owner) –
Disappointed with condition. Advertised as “good condition,” but it arrived with significant rust on the underside and a noticeable dent on one side that wasn’t in the listing photos. It’s still usable for my low-priority storage, but I feel misled.
