Input: This is a great product and very high quality. Not sure why the price went from $120 to $100 in two days. I would say that it is still worth it. My only complaint was its size. It's larger than my average key chain, but not really a space saver. Would definitely recommend, especially for those with many keys you need access to. Very good quality product. However, if the seller had offered an open box, I'd have gotten one just like it, or even something smaller instead.
Output:
Good Review
