I am new to steaming games and had became a fan of Luna. The controller for perfectly in my hands andI can hold the controller for hours with feeling fatigued. The setup process was easy and straightforward, and did not take long to connect to the cloud. I enjoy playing the games in their cloud library and hope more come to the cloud.

The controller is solid, feels good in the hands, and functions quite well with no noticeable lag. It functions to control my Fire Cube in normal mode, and switches to Wifi when I start the Luna app, taking several seconds to do so. Once in Wifi, it works well in games, yet still controls the Fire Cube by voice (Alexa).

All-in-all, I'm pretty pleased with the device.

One minor flaw is that the markings on the buttons are a little difficult to see for those of us with "old eyes" in dim light (it's always dim when I'm gaming!)

I also wish it was rechargeable. I haven't used it enough to wear out the batteries yet though, so that may not be much of an issue. However, based on other controllers, I initially assumed the USB port was for recharging. It's not.

04/01/2023: After writing a review yesterday, berating this device for failing at 11 months, an Amazon tech called me this morning asking for additional troubleshooting. We spent about a half hour going through stuff to no avail. It simply would not connect to my network anymore.

Afterwards, I dug into my network settings and discovered I'd blocked a device which showed on my network as "UNKNOWN". So I un-blocked that and tried again, and this time it connected to my network.

All my other Amazon devices (and I've got many) identify themselves as "Amazon-" followed by part of the MAC address. So when this one didn't, and my router told me that "UNKNOWN" was connecting, I must have told it to block.

So while the blocking was on me, I maintain that if it had identified itself as an Amazon device, I'd have figured out which one and not blocked it.

While the tech did not identify the exact issue (how could she - it's MY network!), her efforts were kind, patient, and in the end led me to the actual solution. So big kudos to her! And to Amazon for taking the time to contact me when I'd pretty much given up on this device

For a controller, I can't speak for it, but for online play for streaming games this is your best bet. I got it and ended up returning it because my TV didn't support Luna and now it does finally. So I can't wait to retry all of this. You need a game mode with the product you're playing with along with this controller and that will minimize the lag to nearly unnoticeable playing FPS. But the game mode helps and we don't have those in Samsung's tablets or iPads for that matter. But if they did and Luna can get them to get the tablets to go into game mode, this thing would be unstoppable for streaming. Especially with a good TV or a good monitor, the graphics outdo the consoles. Just waiting for that 4K to kick in. But this controller does what it's supposed and it does it well. With a direct connection to the cloud, it definitely saves on lag by at least half. I am the pickiest person when it comes to lag and, it wasn't unplayable, put it that way. This is a good buy if it's on sale and you have prime. You got your random games a month

I wish this would have had a charging card but it does work. Buttons are little hard when pressing but gets the job done.

One of the reasons I bought this was to use when I travel and stay in hotels which I do quite frequently. However, I could not get the controller to connect to hotel wifi networks which kind of renders it useless. Other than that it seems to work as intended around the house.
