Slightly disappointed
Size: 4-Tier (10.43"x14.17"x45.67")
It's just wonky....
I wanted something to shelve puzzle boxes and thought this would be a great option but I'm slightly disappointed.
As I tightened the last round of screws, I hope it would straighten out but it didn't.
I triple checked the numbered pieces against the directions and everything is where it should be.
I may dismantle it to return it.

Well made kitchen caddy
Color: Black, Size: 9.4*4.1*5IN, Color: Black, Size: 9.4*4.1*5IN
Appears to be well made. Just the right size, not too large or small. After purchasing and returning several caddies. This one is the keeper. I'm sure be just as pleased as I am. Go for it , you won't regret it.
