I gave 5 stars for battery life, but I truly can't say yet as it's still brand new. I've only been using this for about a week, but so far so good. There have been a few times the mouse doesn't respond, but it's only for a split second and doesn't stay that way. The spinning wheel for scrolling does feel a bit cheap and I'm concerned how well this will hold up through the wear and tear of normal everyday use, but it's doing okay so far. As far as looks go, it's super cute. I was in the market for a slim mouse and when I found this one with many different colors I couldn't pass it up. Overall, I'm satisfied with the purchase and would purchase it again.

I like the dress but was very disappointed that it came torn right on the front so it can't even be hidden. Edit: I would like to add the I've bought several dresses from this company and this was the only one I had an issue with. They were very polite and I would recommend buying from them.

I love the quality of the product and the nice rain shower produced by it. Including a high-quality metal extender arm was a nice plus. I also bought a valve on Amazon that allows me to toggle between the fixed shower head and a handheld one-it also allows you to split the water stream. With this setup, it's like being on vacation at an expensive hotel. The shower head will require periodic cleaning to ensure that the water nozzels are not plugged, but that takes only a minute.
