If you want to be scammed by all means try them out. If you don't, then STAY AWAY! Phone goes straight to a voicemail and emails DO NOT get answered! They are NOT what they claim to be.
Tip for consumers: It would have been nice to know that you will NEVER get any sort of communication from them. Calls go straight to voicemail and emails go unanswered. STAY AWAY!! $500 is A LOT of money to loose!
