Pros: Paid surveys usually available, immediate cash out to PayPal, works pretty well on desktop PC. Cons: A handful of surveys don't work well on iPhone, sometimes glitches during session and your booted out of survey, cash out only to a VERIFIED PayPal account (account needs to be linked to a bank account or PayPal credit card, not just simply a credit card), surveys sometimes asks for very personal info, some surveys are way too complicated to justify payout (eg. How many square feet of roof underlayment did you install in the last 6 months?), many surveys ask for personal info and then says you're not qualified to take survey, alerts to new surveys don't work very well so it's better if you just check Qmee often. Overall, Qmee works but not as fast and easy as Google Rewards.
Update: I've encountered some surveys that are very deceiving. After taking what appears to be the actual survey (not qualification questions), the survey ends with "sorry but not qualified to take survey"...meanwhile, I've put in time answering all the questions and even watched the video. The latest one of these deceiving surveys is one I just did that made me so annoyed that I decided to update this review. It was for "American Gods", a series on Starz. I wish there was a way to report dishonest surveys like this. I hope this app developers would consider it. Fortunately, I've only encountered a handful of these bad surveys, most have been honest.
