Run by Fool CEO (and co-founder) Tom Gardner, Motley Fool ONE is often called the "crown jewel" of Motley Fool services.

But before deciding whether Motley Fool ONE is something you want to consider adding to your investing arsenal, you should read some reviews on it. (And not just on, by the way – there are plenty of other websites online that have relevant reviews of the service.)

We've compiled some Motley Fool ONE reviews that we thought were particularly insightful – reviews that, when combined with knowing the underlying structure of the service, can help you decide whether it's right for you.

Fool ONE reviews on investing style

Our goal is to provide you with the information you need to make whatever decision is right for you and your family. Learning about our underlying philosophy should be a big part of your decision in purchasing this or any stock subscription service.

Fool ONE member Larry S. notes that "The investing philosophy that Fool One emphasizes of actually being a part owner of high-quality companies and focusing on the long term is extremely helpful. It helped me gradually stopped looking at stocks as little squiggly lines attached to charts but rather quality companies to follow and study and think of ourselves as a part owner of for the long term."

Let's emphasize that again: We're buy-and-hold investors, and we strongly believe in buying stocks for the underlying companies. And Fool ONE's Everlasting Portfolio is a key example of us eating our own cooking. The stocks in the Everlasting Portfolio are the only stocks Tom Gardner will buy in his own private portfolio – and the Everlasting Portfolio must hold its stocks for a minimum of five years.

Several members note that knowing we were this aligned was a major factor in their decision-making around Fool ONE. For example, Jane S. says that "I feel much more confident knowing these are 5 year buys and wise people are advising me --- folks whose philosophy jives with my own."

Freedom, Motley Fool style

Freedom means different things to different people. Some Motley Fool ONE members are seeking freedom from the rat race, and the powerful optionality that investing can give them. Such is the case with Fool ONE member Mark T., who notes that: "For the first time, the money that I've invested has grown on top of itself and is making more money than I make now. I think that's a goal that a lot of people aspire to, especially to become financially independent, is the money that I have now is working harder than I am at generating an income."

Others are seeking a service that can just make their investing lives easier – so they can confidently invest in new companies without having to get into the nitty-gritty of extensive research. Bob F. told us that "What Motley Fool does is it makes it so I don't have to bother worrying about earnings per share and P/E ratios or even finding the companies. They find the company, do the analysis, give me a recommendation. In two minutes I can read it and say, 'Yeah, this fits. No, it doesn't fit,' and move on. I don't have to waste a lot of time figuring out what I want to invest in."

How would you use Motley Fool ONE?

Some investors are drawn to Fool ONE because of Tom Gardner's underlying investing philosophy. Others join for the Everlasting Portfolio. Still others for the "all-access pass," which enables them to engage with any service in the Motley Fool universe – basically, an all-you-can-read buffet of stock and options picks, deep company research, and analyst market insights.

But ultimately, the choice as to how to use such a diverse service is yours. If you're ready to learn more about Motley Fool ONE, click here.
