The mouse wheel makes an incredible noise, it can be heard in another room. As for the keyboard, it was okay at first, but after a short period of use, the keys have hardened significantly, resulting in hurting your fingers while typing! The positive thing is that all the keys function properly during typing!

Perfect mouse, combines scrolling with automatic middle click.
As for the keyboard, it is ideal for lovers of surprises as while you type, it never ceases to surprise you with letters that you have pressed but mysteriously disappear from the text.

It is basically a disposable keyboard. As soon as I opened it, the two keys were pressed further inside, they didn't make the click that keys normally make. I returned it and they replaced it with another identical one. This was fine for about 3 days. Without even using it for typing, with very light daily use, various keys started to have the same problem. You can see an example of this here. Many times, even when I press the keys with a lot of force, you can see that the letters are not being pressed at all. Sometimes the "t", sometimes the "k", sometimes the "a", etc. The Lamtech keyboard is a disappointment, just like the mouse. I don't even understand how such disposable products are allowed to be produced and sold as regular ones.
