Amazing that I can get 30 games for a little over the cost of 1 game in the 1980's (and that doesn't account for inflation!).
The unit comes with 1 controller, and if you've read the online reviews, you know the controller cable is too short. Living rooms today aren't like living rooms of the 1980's, to avoid a "midpoint" stand for the Nintendo Classic I highly suggest ordering an extension cable just so the cables are not hanging in mid-air.
The unit itself does come with a wall-supply, but with the micro-USB power, you can actually power it directly from your TV's USB port or in my case I use a USB port from my Xbox One. I love this feature!
The controller feels totally authentic. One issue I had when using it was that I thought the controller was "laggy". It turns out that modern flat-panel TV's are laggy, not the controller. You have to go into your TV settings and change it from "standard" or "movie" to "game mode". I'm sure the gamers out there know this already. If you are getting this for a blast of 80's nostalgia, make sure you switch your TV or otherwise games will be unplayable.
Other than that, this is the real deal - totally authentic. Plus - you can save "state" in the game at any point. Want to beat Gannon in Legend of Zelda? You can actually save your state right before you get to him. If the fight is going well, save the state again! Start losing? Just load the state from when you were doing well. The entire menu system is very well done and quite intuitive.
I'm sure there are dozens of games we all wish were included that were not. I won't really knock the system for not including every variant of game we can imagine. However, I was disappointed to find Tetris was not included. And the architecture of the box doesn't allow any sort of upgrades (unless that USB port isn't only for power?).
Overall, it's a really fun box for $60. Why 4 stars? Well, you will want a 2nd controller to play with a friend. So throw in another $10 for that. Then both controllers will be too short, so you'll need $20 in extension cables. Taxes and shipping, this will really be over $100 just buying it all retail. I would have preferred a slightly more expensive box that included the controllers and proper length cables. I'm also a bit disappointed there can't be more games for this platform when they clearly could have designed that feature in there.
But do I recommend you buy it? In a minute - it's so much fun. But just spend $60 - don't pay these crazy prices. It will come into stock eventually and you will be able to get it for $60
