The lock-rods were a little stiff. A bit of WD-40 fixed them right up. Probably from sitting in a yard.

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.

Started a container garden! Bought a used one, drilled holes for drainage, and now have raised beds. Creative uses are endless!
Caleb Zhang (verified owner) –
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.

Took a long time to process the order. The container was in stock, but it took over two weeks to get it scheduled for delivery. Once scheduled, it was fine.

Great product, minor delivery hiccup. The container is perfect for our needs. The driver was great, but the delivery window was a bit wide (8am-5pm). Would still recommend.

Patrick O’Brian (verified owner) –
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.

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

On-site storage during renovation. Lifesaver! Kept all our furniture dry and safe for 6 months. Easy on/off-hire process.

Wind and watertight, just as promised. We’ve had torrential rain and high winds, and the inside is bone dry.
Beatrice York (verified owner) –
Okay, but had an issue. The container we received had a small leak around one of the corner castings that wasn’t apparent on delivery. Customer service was responsive and sent a repair crew out within a week to fix it. Problem was solved, but it was an inconvenience.
Vincent Costello (verified owner) –
Took a while to get a quote for a custom mod. Standard container purchase was easy. Asking for a quote on a custom door took a few follow-up emails. Eventually got it and it was fair.
Yuki Nakamura (verified owner) –
Very good overall. The container itself is great quality. Delivery was a few days later than initially hoped, but the communication was good so it wasn’t a big issue. Four stars.
