In order for this service to make sense, they would need to deliver returns that are at least 1% in excess of say the S&P 500 index performance. One quick way to verify is to test it. Put some amount of money in their care and see if their performance (minus fees) exceeds what you can get in a passive index. Also keep in mind the compounding effect of the fees towards your returns over time so the excess return required will likely need to be much higher than 1%. I'm too lazy to calculate it right now but you should be able to easily model the impact over 5 to 10 years.
