The company is legit and they do pay, but for me I consider this extra money only. I would never ever depend on it full-time. However, it might be possible to make an extra $50 to $100 per week doing this depending on how much time you can put in, so if that is all you need to make, then who knows, maybe it's for you.
I would still recommend having a few other things to do to earn money on the backburner as well just in case calls dry up completely. One thing I've learned after working at home for so many years is that it's not safe to depend totally on any one thing!
If you're looking for actual, legit work at home jobs that could equate to a real paycheck every week, I recommend getting a membership at FlexJobs. I have been a paid subscriber for almost two years now! It's only $15 a month for access to hundreds of guaranteed, scam-free work at home listings and absolutely no ads on the site whatsoever. It updates daily, and I've had many happy readers let me know they found jobs using the site.
