In my opinion, this is a scam to get your credit card information. I used this service once and on the very first time I used it my credit card was charged repeatedly. What's worse is that I cannot delete my credit card from the app. I now have had to contact the credit card company to start my card from any future payments. My credit card company is also assisting me in trying to recoup the money that was taken out of my account without authorization.
Be very aware of what this company really is.
Bottom Line: No, I would not recommend this to a friend
