I have it (for the last few years) with the Fidelity discount.
Use it every day, and find value in the couple of $ it costs me each week. Of course, maybe since I'm retired I may look at it as "entertainment

".
Anyway, it's in my budget (I'm anal

) and will continue to get it in the future.
I've found it a good tool to "teach" my DW about our portfolo, beyond just the style box. Showing her where our investments are "in the world", showing our portfolio mutual fund expenses (real eye opener!), ROA, ROE, EPS growth, and current yield, along with how we "size up" to other portfolio models gives her more knowledge and ease of information gathering than what you can get "for free". Of course, you could possibly do extracts and Excel formulas to get the same info, but for the price, I'll let others "do the math".
Just as an example, she (along with everybody else) was complaining about the price of fuel. She complained that somebody is making a lot of $$$. When I showed her that our holdings in a "top oil company" was held by six different funds (by multiple fund companies) by simply doing the "stock intersection" on M*, she saw that she (may?) be getting some return on all the money she's putting into her car gas tank.
Again, most folks could probably get away with some of the "free stuff" on other sites, but the M* site has a lot of information (and 7 different premium tools that you can't get without the subscription) that IMHO is a "cheap price".
Nope, don't work for M*

Just a "satisfied customer"...
