I have Square. I like it so far. What I don't like:
-No customer support number to call if you have a problem. Yes, I said NO phone number. If you have a question, you have to email and wait.
-When you're starting out, they will only credit a certain amount per week to your account until they, "verify," the account you're depositing your funds into. Can take 30 days to collect the rest! I really don't like this as other companies I've used do not make you wait so long.
-The reader is tiny. Partially a good thing but easy to lose the reader because it's so darn small.
Overall, I like the idea. I was using Intuit--which I loved--but hated paying the monthly fee since I would use it in spurts and not use it for a few months. I love being able to use my phone to take payments. Very convenient.
