Question: Has anyone experienced rust on the metal parts of this caddy?
Document: The only thing I am concerned about is the metal spring and screws, but I am hoping OXO had enough sense to use rust-free parts. If not, I will surely update this review in a few months.I really love this shelf and heartily recommend it to anyone who has, like me, been looking for something to fill such a role and is tired of all the junk that floods the market.=====================UPDATE!
Although my wife doesn't have many round bottles, as they do not seem to make this style as much now, if she does have any I am sure this option will be put to use. There are also 2 metal "hooks" to store something like a razor.Overall, this one is worth the money as it is going to last a long time and you are going to get a lot of use out of it. We would recommend this OXO corner caddy to anyone in need of more space in his or her bathtub/shower.
At first the rust appeared in only a few places (on the hooks for razors). But now it's everywhere. Why did they use metal?Too bad - I really like this caddy. It holds several shampoo bottles and stays on the wall. But the rust makes this shower caddy a mess.
And if it's in the wrong place (or you just don't want it anymore), it's very easy to remove. All around, a terrific shower caddy.November 2013Well after 11 months, I'm downgrading this caddy from 5 stars to 2 stars.Unlike some users, I haven't had any issues with it falling down. It's stayed firmly in place.However, I've had a problem with rust - the metal pieces that are a part of this shower caddy are covered in rust. The rust started appearing after about 6 months of use.
So, as soon as my package arrived, I whipped out the Corner Caddy and took a look at it. It does look exactly like it does in the picture, and it feels fairly solidly made. The plastic feels strong and sturdy. I was concerned before ordering it about the metal bar that's on the front because nowhere on the item description does it say what this metal is. Is it chrome? Is it steel coated in chrome? Is it aluminum? I'm hoping it's made of something that won't rust (especially since this caddy is meant to replace a shower shelf rack that's practically rusted to pieces).
I have tried it ALL!! Every shower caddy I have ever owned has driven me nuts! Not enough space, rusts too quickly or the worst....everything constantly falling over!! Bought this on a whim (30$ seemed steep) but I am so so glad I did. There is no suction cup needed, (thank goodness cuz they NEVER hold!) It locks into place and will not let go! Holds lots of stuff weight wise and space wise and there is almost no metal so rust (if and when it does appear, tho it hasnt yet) will be minimal and easy to clean!
I really wanted to like the OXO Press Sure Corner Caddy because all of the metal shower caddies I seem to buy always rust. However after trying it for a few days, I ended up getting rid of it. I followed the manufacturer's instructions, and when I first set it up, it stayed. However, as soon as I took a shower, it would slowly slide down the tile wall and eventually fall. I only put lightweight items on it: an Organix shampoo and conditioner bottle. I tried this for a few days, only to see the same result.
I'm not sure what sort of metal it is, but I hope that rust won't be an issue over time. The only other question I have is: how secure is the gripper, and does it have to be reset sometimes? Time will tell, but the OXO is quite securely in place right now. It seems well made, and should provide many years of service, but if I see any problems in the future, I will note them here. For now, I recommend this product.
Easy to adjust. Very sturdy unless you elbow drop it like Randy Savage. The top one (which has NOT been bumped) is holding strong, and has been, for over a year.Cons: It did start to show some rust on the metal part within the past few months, but that, I believe, is largely due to the fact that my bathroom does not ventilate well. Would probably not withstand a bathroom with grabby children unless you installed them very high up.
:)I will make sure to come back and update the review if I notice it falling or any degredation of the rubber stops on the edges.UPDATE, Mar 2013:  My 2 shelves degraded and the plastic failed at the point the 2 little pegs snap into the rubber bumpers on each side. I knocked off a star because they barely lasted one year. Granted, I think I had the shelves a little overloaded, but the tiny plastic pegs should be bigger/stronger - it's a huge failure point. I also have some rust where the metal joins the plastic for the razor holders and metal rim.
Answer: I've noticed some discolouration with the metal parts that are embedded in the plastic.
