Review title: Be Aware
Product review: I purchased this item as a replacement and installed it according to instructions. It failed after four months. The instruction manual included with the device is in Spanish. I can read Spanish as long as it's not too technical. Oops! I got three at the same time, so I'm going to install another new one, but prospective purchasers should be aware. These devices seem to have problems, and if you're going to fix them yourself, and don't read Spanish, you will need to download the online manual.
