Pros
- Looks like the others — because it is: the same shell four brands sell
- 'Love the size and look' — the first half of a two-star review
Cons
- The claimed 370 gallons is larger than the box's own exterior volume (318 gallons from the listing's dimensions); the same seller, ARTS BOX US, sells the same 67.72 × 32.2 × 33.66 in shell as '320 gallons' under the Yardgrace name
- 'It blew apart in a wind storm. This is a plastic snap together plastic box. If you buy it reinforce the box with wood braces on all corners'
- 'If you put any weight in the bottom of it, the bottom of it sags, and it pulls away from the sides'; 'has already started to bow in the front' after two weeks; 'the sides are bulging' with cushions alone — 31 critical reviews, 15% one- and two-star
- No brand site (tarkari.com parks to a lander), no warranty; the listed weight (30.9 lb) is less than half what the same shell weighs on its sibling listings
