Good for organization, looks neat!
Color: 2 Tier-Black
I've had this for almost a year now and expect to have it for a few more; seems very durable. The drain board thingy requires consistent cleaning every few days, but its done in less than two minutes. I usually wash the entire thing every two weeks to keep it shiny as well. I am seeing a little bit of rust, but it's not too much and it's not noticeable if you don't look for it. It's great for organization and was easy to assemble. A very sturdy and well-sized product.

Serves purpose and holds what it was intended to
Color: 2 Tier-Black, Color: 2 Tier-Black
I like it. Keeps things organized and handy in small kitchen. The attachable bin holding my brushes I put on outside of unit not inside as company pics show it. That bin only has one clip to hold it in place. This makes it a little wobbly if you want to place it on the outside like I did. I used 2 trash bag twisties to help tighten it into place. Doing this made it no longer lose and the inside area space larger to hold both of my soaps. Fits everything I need it to. I appreciated the little lever on bottom that moves for water drainage. My sink design doesn’t work for the other drainage design I found these to have online.

Great sink organizer
Color: 1 Tier-Black, Color: 1 Tier-Black
I've been searching seems like forever for something to make my kitchen sink look more organized and this caddy solves my problem!! I found a different use for the basket that holds a scrub brush since I don't use one of those. Nice design that fits my kitchen objects and no worries about removing a tray to empty water out. I used the adhesive holder to attach it to the wall behind the sink but one corner is peeling off, causing the basket to hand on that side. :( It would have been nice to have a replacement for that, but overall I'm pretty impressed with this thing!!
