It's the fees rather than the quality of advice that is the issue. I have had a few colleagues use them, and the fees were something like 5% - 7% from the initial investment, up to 1% annual fee for "ongoing advice" (when mostly invested in passive funds), and then they would invest in their own funds which would have their further fees attached. Very difficult to see the full cost of their "service", but I reckon you'd give your annual investment performance a 3% head start by using a lower cost provider.
