I believed it's really common that all crypto ATM's is usually associated with fees higher than the average fees when dealing in exchanges but how much "fees" we are talking here pointing to Crypto ATM's there?

If using ATM's will save you from hassle way, trouble or risks and will give you convenience, comfortability and instant transaction, then I think you should consider using those especially if the fees don't have a small difference to an online exchange service.
