Question: Can you remove the back metal hook part and just use the suction? I have a small sink and I want to affix it to my backsplash.
Document: I love the brushed stainless look, it functions well, and you can take it apart to clean it. I don't use the metal bar on the back simply because it didn't fit anywhere in my sink with it on, but my sink is rather small. The expandable brush holder seems superfluous to me. Whether it's expanded or collapsed, it really doesn't seem to affect the overall area left in the sink. I've read some reviews about the suction cups not working but I haven't had any such issues.
I have a sink made from composite material and the suction cups just do not work! Additionally the metal hook is not properly designed, if it had a bend in it I could have placed it over the center part of the sink and it would have stayed in place. If you have a stainless steel sink it will probably work fine for you
Does what it's supposed to. It helps to put vaseline on the suction cups. The finish is easily spotted when water touches it, and it comes with a sticker on it that leaves a big dark oval mark on the brushed metal finish right in the middle of the curved part that you can't ever get rid of. But it's functional and has a lot more room than most other sink caddies. You can take out the divider if you want to.
With the metal support bar tucked until the bottom of my dish rack it doesn't much matter that the suction cups don't stay stuck all the time.I use this with a 10 oz (smaller) bottle of dish soap in the cup part, without extending the silicone cup out of the bottom- as shown in the product photo). Holds two sponges and soap so that the counter stays clear!
I have a double bowl stainless steel kitchen sink and since I have a dishwasher the sinks don't  see a lot of dish washing action. I have a dish drainer in one sink which I use for rinsing out the recyclables and storing scrub brushes and sponges. I thought this caddy would work better than using the silverware cup in the dish drainer and keep them out of the pile of cans that accumulate there. I had to remove the metal hangar as that was impeding the space on the top for my hand soap dispenser.
I purchased this product for my home kitchen. The suction cups that affix the holder to the sink can get very dirty and sometimes falls off. I have to remove the holder and clean it often.
Hi all, this looks great, but I would really like to know the diameter of the round hole where the scrub brush is supposed to go. I keep a small plastic nozzle bottle for detergent and that is what I would use it for. Would anyone be willing to measure the diameter of that space and report back with a comment? Thanks!
I'm glad I went ahead and purchased this product despite the reviews that said it falls...cause it stays up perfectly!! I've had it in my sink for close to a month and it has not fallen even once, and I didn't put any weird product on it. The metal part that rests on the edge of the sink has some sort of rubbery covering and that adds so much support that the suction cups are not challenged in any way.
i love the look and feel. I am becoming a fan of simplehuman. But the suction cups came off 30 min after i put them on. Maybe i didn't put them on strongly. Now they are back again. will watch. Space wise, its nice. Looks very nice. I just do dnot want the suction cups to keep coming off.
The kitchen sink caddy is well made, functional and attractive. I can not address its durability as we have had it for only a couple of weeks. A portion of the weight of the contents of the caddy is supported by a metal frame that extends over the top of the counter which supplements the support provided by the suction cups on the back of the caddy. We were very pleased.
Answer: Yes.  Squeeze the ends closer to each other and it will come off.
