Do you have any experience with it? If yes, you mind sharing some words?
I have used it for about two years for medium risk investments (~12%) and have had no losses so far.
It helps that many providers have a "buyback guarantee" that automatically repays you for investments if the payment is late for more than 60 days.
I just transfer an amount of money there every month, and the auto-invest feature just picks investments across providers.
I hope it helps, but feel free to ask specific questions if you like :)
