    • Good choice if you can’t get a wooting
Color: white
Good quality build. Not the best, bad for how much it costs it’s a bit pricey, for 3 keys. the switches that come with are super annoying, but buying replacements is so easy that it’s not an issue. Very quick and responsive, not too wooting speed but probably second best. really portable and can move it out of the way at any moment. software is fine too. ... show more

My son enjoys this tool. He spends hours using it to play games. He finds the claacking noise it makes wildly appealing. It was easy to set up.
