I have been using MTG Manager for a few months now and it has greatly improved my card collection organization. The website manager.mtg-ar.com is great and offers an intuitive interface that allows me to easily keep track of my cards. The search feature is particularly helpful when trying to find specific cards. Overall, I am very happy with MTG Manager and would recommend it to any Magic: The Gathering player.
