Pros
- A manufacturer, a direct store and a warranty page — the only one of the five with any of the three
- Metal, not snap-together resin: no bowing walls, no bottom pulling away from the sides in the tail
- Wheels on a 120 lb box, and a claimed capacity that sits well inside the shell's 340-gallon exterior
Cons
- 'The sides come bent which makes them difficult to put together (this was not a packaging problem. I bought two and each had both long side panels bent)'; 'the screw holes do not line up'; 'thousands of screws… I still messed up the lid hatch. Once you get it together, they make it impossible to go back' — 17 critical reviews and a 13% one-star share
- 'Both of the lift pistons for the lid' failed on one owner's box; rivet nuts strip if the driver is off vertical
- At $599 it is nearly three times the class price, and 281 gallons is under the 300 mark the rest of this page is sold on; the maker's 370-gallon Urban is $899 direct and not on Amazon
- The rating pools four sizes and two colours; 134- and 175-gallon reviews sit on this page
Assembly of a bent metal kit. 'The sides come bent… I bought two and each had both long side panels bent'; 'the screw holes do not line up.
