Perfect placement of my iPhone for GPS usage on my dashboard and it stays firmly in place.  I like the fact that I look at it and still keep my eye on the windshield.  It was easy to attach and fold flat when not in use.  Everyone who has been in my car with me is very impressed with it.

Fast, easy, simple and effective.  Great way to add lighting to an outdoor area such as a driveway or approach to a door in minutes.

These are excellent.  They do exactly what they are intended to do.  They are not super strong, but they seem certainly strong enough.  I like them a lot based on the combination of their functionality, simplicity, and simple design.
I would and will buy these again.

So simple to install. So, so simple.
I don't care what all these other reviewers say about this item. It is the best item!

No, seriously. It's effective, the water that comes out is tasty, it is easy peasy to install, and it looks handsome in the kitchen. Takes up very little under-the-counter space (important if you want to keep other things under your counter, but you already knew that) and works 24/7. Takes care of business.

Simple and effective. I can see lots of paw marks on the bottom from racoon attempts but this does seem to baffle them.

Simple yet effective. I have two of these (one in each bedroom) and they're fantastic. Very easy to install.
