It is very easy to use and it works fast. I can find my contact list very quickly. I like that you can download a CSV file with all of your contacts. Sometimes I get an error when I try to create a new profile but that's because sometimes the site loads really slow. Try it out! You won't be disappointed! This helped me save much time as I had previously saved my contact info on various other sites but this was the best option. It helped me stay organized so that everything was in one place. I like how easy it is to use with an iOS app as well! There aren't any cons that i can think of so far but if you are looking for something simple then this could be your favorite tool out there!! If someone told me they want their contact list organized into groups like "people who live near them", etc., would have been really helpful when managing my business connections on social media platforms such as LinkedIn & Instagram @lucasgfrancois.
