The best part about this tool is that it can be used without downloading any software. It works well for me because I am able to use my computer to access all of my contacts. This also makes it very easy to share my information with others. There is nothing I dislike about this tool. If you want an online database that is simple and easy to use then this is the right tool for you! I love having everything in one place so I don't have to find different places to put my information. I'm also able to update my information easily. Having everything in one place is great for me because I don't have to search through multiple places to get the information I need. I can now store my contact information in one place so I never lose anything again.
