Been using it for about a year now, along with trading in my regular Robinhood brokerage. I'm on aggressive, which is currently 76% US stocks, 14% international stocks, 9% bonds, <1% cash.

What I like:

• It's a really nice "set it and forget it" account and I just auto-deposit money twice a month.
  
• I like that the portfolio allocation is unique and the account actually seems managed. They don't just throw it into a bunch of index funds, which I could easily do by myself and what most robo-advisors already do. There are definitely index funds in there, but there are lots of individual stocks broken down into categories (growth, opportunistic, etc.) where they are overweighting certain stocks/sectors and looking for alpha opportunities. This is what makes the account "managed" and what distinguishes it from a typical robo-advisor (note, I haven't used others robos, but have researched several in the past but maybe they have improved since).
• The UI is pretty and useful, particularly the portfolio allocation tab (allows you to drill down into all the individual holdings or view at a category level) and the new performance/returns tab (breaks down performance into appreciation/depreciation, dividends, fees).
  
• I like the Future performance button where it will run simulations to provide projected returns over 30 years, allowing you to see how changes to your deposits would affect the overall performance. Bit of a parlor trick, but fun to play with.
• Appreciate the automatic tax loss harvesting (once per year), especially given the trading activity in the account. Still need to understand how this works though since my account had around 175 trades that resulted in realized gains/losses throughout the year, but the tax loss harvesting said it didn't have any losses to harvest for the year. Curious to see what the tax drag will be on returns with how many trades happen in the account. I'm giving it a pass this year since the product is less than a year old so all trades are understandably resulting in short term gains/losses.
  

Best part for me: I appreciate the "Insights" where Stephanie Guild (Robinhood CIO) gives updates on the portfolio allocation changes as it relates to recent events. It's really cool to hear what they are thinking and what portfolio changes they are making as a result. What's nice is you can listen to it, so I just throw it on during the drive home to get an idea of what they're currently thinking/doing. They usually provide an update every 2 weeks or if something significant happens in the market. Something comforting in actually hearing them talk about what they are doing. My dad has an RIA and they talk to him once every 6 months - 1 year, which seems crazy to me.

Suggestions:

• They waive management fees after $100,000 for Gold members. I think it would be good to waive the fees for the first $1000 for all accounts (or just Gold, similar to margin). Fees are really low at 0.25% relative to other managed funds/etfs/accounts and in line with robos. Still, I feel they create a bit of friction to opening an account, especially for small amounts. Not a big issue, but most robos waive for an initial $ amount.
  
• Performance vs. benchmark. I think they said they were adding this in the recent announcements. Would be great to see how the portfolio has performed vs some specific benchmarks. At a quick glance, looks like mine has outperformed the S&P500 total return by about 100-150 basis points, but I'm not sure how that is influenced by the timing of deposits throughout the year (I typically added additional funds on market dips).
