I purchased this as a replacement for the same make and model that was originally installed with my unit 5-6 years ago.  The original had not been working for some time and it turns out the when the product was made, they used plastic pieces in the interior reader that are subject to break.  I ordered this replacement and was please to see that the plastic piece inside is now made of a much better quality (and hopefully) longer lasting metal material.  One of the main complaints in the past about this product was the poor quality due to the plastic and it looks as though it has been upgraded.  So far everything is working great and it took me about 3 minutes to replace the old one with this model.
