Pros
Cambly is a great place to meet people from other countries...and make a little extra cash while doing it! I love that it is completely flexible. There are no lessons to prepare and no set schedule you have to follow. Many times I have been lazying around the house, surfing the web and I log in to my Cambly account just to see if anybody is out there. Many times people have called in and I get to have a wonderful conversation with someone on the other side of the world. A 30 minute conversation is 5 bucks! Easy money and I get to talk with some cool people. I have yet to have a bad conversation. I also have regular students who make reservations for me and I can go through some actual lessons with them. Cambly has a huge library that has all kinds of material to use if you want...and its all free. I have absolutely enjoyed my time on Cambly and would stay on it all day, everyday if I could. Sure, you don't make a ton of money each conversation, but it adds up. If you really like talking to people and helping them out then it isn't really about the money. However, it is nice that every Monday the money earned from the previous week goes straight into my Paypal account. It isn't hard to figure out that this is a sweet gig.
Cons
I and some students have had issues with internet speed. Not Cambly's fault, but they do fuss about have some good internet. Completely understandable if they want to keep a high level of quality.
