How to read a Showdown Score™
The only score that counts how often a product breaks, not just how owners feel about it.
- Three parts add up to the score: what owners rate it, how often it fails them, and whether a credentialed tester backed it.
- Bands: Exceptional 8.5 and up, Excellent 7.5, Very good 6.5, Good 5.5, Fair 4, Poor below 4. Every score is dated.
- Price, the warranty and what a link pays us stay out of it.
Very good
Very good is 6.5 to 7.4.

Pros
- About $36 for 30 lockable gallons at side-table height
- 4.6★ across 408, one model pooled across four colours, every visible review a verified purchase, none from the Vine programme
- Owners use it exactly as a side table: "Sturdy enough to double as a little side table for drinks"
Cons
- No maker website, no published warranty: the listing is the only document
- Sold by a Hong Kong reseller (Youmi Electronic Technology) at 75% positive feedback over the last 12 months — not the GUNJI trademark owner
- The 30-gallon label matches the outside of the box (22 × 16 × 20 in = 30.5 gal), so the inside holds less
- The lid warps: one owner's "started to warp so the lid no longer fits properly"
- Lock holes too small for anything but a cable lock, and ants got into one owner's box
- The seller charges return shipping
A thin shell that warps. "Not very sturdy once assembled… doubt plastic hinges will last", "Too thin and Flimsy", and a lid that "started to warp so the lid no longer fits properly". It is "water resistant", one owner stresses, "NOT waterproof", and "the holes to put a lock in are too hard to get a lock in, other than a cheap cable lock". One found ants inside; one was charged return shipping.
