Doba.com — I'd recommend against trying it, unless you like the thrill of waiting for their phone calls
I was curious about the 7 day free trial was entering my information in when they asked for my credit card info., so I googled some reviews and realized it was probably not going to be a good idea. I closed the browser and didn't sign up. The next day, I get at least 3 calls from them with a voicemail telling me to sign up for their promotion of 14 days free. I hope they stop calling me because I read on another site, that they've been receiving calls from them almost every day...and it's not possible to block numbers unless you pay $4.99/month if you're with AT&T so I'd recommend against trying it, unless you like the thrill of waiting for their phone calls.
