I've been using the door closer key from mvsafe.com for a while now and I must say it's been a game changer. The key is so durable and easy to use. It has definitely improved the security of my home. The customer service provided by Mountain View Safe was also very impressive. They were prompt in responding to my queries and provided me with all the information I needed. I highly recommend this product and company!
