Pretty good, but requires some effort to stick

I've been a fan of Umbra's designs for quite some time and have purchased stuff from them in the past (picture frame and dish rack), I'm always consistently impressed with their design and quality. This shelf is no different. I'll admit, like others, I had problems with it at first. I was nervous and whenever I checked it seemed like it was going to fall down (the cups were loose). There's no reason for that since my tile is only barely texture at the bottom and I have large tiles, so I gave it another try and it's working great.

The secret?
1. Clean tile. Put a little water on the suction cups.
2. Don't put anything on the shelf at first after you apply it. (Apply following directions)
3. In an hour or two, revisit it and tighten the suction cups if they have loosened.
4. The next morning tighten them again.
5. Put some bottles on there, but continue to tighten the suction cups regularly over time.

I neglected to do this on my first few attempts and inevitably it would always fall. Now it's staying up with a full complement of four heavy bottles and one medium. I would recommend not to overload it though.

There are some really clever design features on this that I love and haven't seen on many shower shelves before. For example, there are drainage holes to prevent mold. The suction cups are slideable, so you can place them on the tile instead of them refusing to stick to grout. (Suction cups will never stick to grout). There's also the 'band' that goes around. It's flexible and rubbery so not only does it allow for rounded or oversized bottle shapes, but you can also stick a razor in the band if you so desire.

At first I had concern, but now I'm confident in it's ability to stay up, I really like this shelf! It might not be right for those with small tiles and lots of grout, or heavily texture tiles, but it works fine on mine!
