If you're looking for a water softener to reduce mineral build up in your water, this is the product you want. I have used RO systems before, and there isn't a whole lot difference between them.

Good Review

I ordered this for my son just prior to his first semester in college and was a great addition to the dorm room. It is as pictured on Amazon so if you are looking at these items, stop right there. Also, there wasn't any instruction manual; however, it took about 5 minutes before we figured out that the top of the microwave had something hanging underneath. There were two tabs underneath one which came off with no difficulty (easily removed by pulling up) but would have been harder without the tabs.

Ex Output:
Good Review

These were great speakers until the power button stopped working. We tried to use it with batteries but that wasn't going well either. Now it's just a blue flash light and that's about it. I am very dissapointed in this product especially since my kids are so excited when we pulled out their new earbuds. I'm returning mine, even though there isn't any kind of warranty on it. DON'T BUY THIS ITEM!!!
