Customer Ratings & Reviews

these razer controllers are compatible for the Samsung Galaxy S21 Ultra 5G.

Have galaxy s10+. Use xbox game pass. No setup just plug amd play. Works great

Exactly what I expected. It fits perfectly over my Samsung S21 Ultra. Now I can stream my Xbox at work during breaks.

This control is one of the best I used for a mobile phone. Even though there are some games that doesn't recognise it yet.

Works perfect with Samsung phone and compatible with all my game.

When paired with my S21 Ultra and Xbox game pass this device is fantastic.

For what it is it's good it just doesn't feel quite the quality for the price. It's not even up to razer standard. The trigger squeak when you pull them and the buttons are mushy kind of sad because they're the third party Xbox controllers they make are quite good

Great little device, used it for playing GameCube emulators as well as Cloud gaming with Stadia.

Great product, works just like a controller, the only issue i have is the streaming which isn't the controllers fault

Excellent controller for android at a great price. It may leave your phone a bit exposed but it controls seamlessly.

Awesome controller... works great for xbox gaming... fortnite is awesome

Best controller for mobile phones. Love the usb c connection. No lag.

Controller works perfectly for my Pixel 6 Pro. Just had to trim rubber bumper for the camera bar.

It's gud. Kinda expensive. Does what it says. For real gamers only!

My family members who received the units liked them very much.

This controller from Razer is a must if you game a lot on your phone. The only thing missing is a headphone port, but I guess you can do this via bluetooth. In the games that are compatible with the controller, using my GS10e, there was no lag at all that I could tell. All the buttons are very well done quality wise. In using the controller, you have to take your phone out of a case, if you use one. There's really no getting around it. The phone is held in the controller via friction fit and to remove it you just have to slide it out from it's cushioned grips. Also the good thing about this controller is that you do not need to charge it to use it. There's a passthrough usb-c port to charge while playing, which is great, but it is not fast charge capable. At least it's better than nothing. This controller is not going to be used by a casual gamer. Sure you can if you want, but I think is a bit of a waste of time to take off a case and set yourself up for 10 minutes of gaming. But if you are home on the weekend for an hour, then this is gonna get usage. I do wish this came with a carrying case of some sort, but I guess you can't have everything. But it did come with some cool Razer logo stickers. It has very minimal packaging which is appreciated.

Razer - Kishi - Gaming Controller for Android - Black Takes mobile gaming to a new level

I bought this for my husband for Christmas and he loves it. He says it's very easy to use and works really well.

Love this controller. It feels comfortable in my hands and works excellent on my note 20 ultra

The kishi is a really good add on for any gamer. Works great with my pixel 3, with virtually no lag. It's portable and light. My issues: it's a little big for my hands (admittedly I have small to average hands for a girl). It wouldn't fit my phone with the case on, and I'm just too lazy to pull my phone out of its case everytime I want to play.
