Small size, number keys, customization, with backlight, Lenovo Savior K7 mechanical keyboard experience

I have always wanted to find a small-sized mechanical keyboard, but the size is right, but the commonly used number keys are gone. I thought I couldn’t have both, but I still let me wait. The rescuer K7 mechanical keyboard I bought is very comfortable. It not only retains the main functions such as the number keys, but also saves 20% of the space compared with the traditional mechanical keyboard, so that my small desktop will not look crowded.

In terms of color matching, there are three colors of phantom black, ice white and ice berry pink to choose from. The one I bought is phantom black, with green keycaps around it, and metal covers with space gray color on the front and rear sides, so that A tough keyboard will appear more dynamic.

The keycap of the keyboard is made of PBT material, combined with the five-sided sublimation process, which has a delicate and warm touch. Even if I use it under high-intensity use such as coding and playing games every day, it will still look like new without oily or fading. Moreover, the quality of the delivered keycaps is the same as the original one, and I also like the individual patterns. I have replaced all these keycaps.

The switch key and charging interface of the keyboard are located in the middle of the top.

In addition, the keyboard can also control the brightness of the light. If you don’t need it, you can turn off or reduce the brightness of the light to increase the battery life of the keyboard.

Speaking of battery life, I have to praise this keyboard. When I first got it, I used it heavily almost every day, and the light would be turned off occasionally. The actual test has also been used for nearly 10 days.
