The worst purchase I have ever made, there is no chance that the keyboard will ever connect to the computer correctly!!!!!!!

The keyboard, after the computer's inactivity for a 5-minute period, loses the first keystroke. Another significant disadvantage is that it does not have a CAPS-LOCK indicator, resulting in having to repeat the typing multiple times when the combination of uppercase and lowercase is not desired. The mouse is quite small and I do not recommend it for users with normal to large hands. It is more suitable for laptops rather than desktop computers. Therefore, the rating is a 3.
I am coming back to tell you that this is a poorly constructed product as after 1 month of use, the keys started to sound quite loud and from what I can see, some will not function in a short period of time.
Another useless product from this specific company, even though I have not paid for products from this company. It is better to go for Logitech, where you pay proportionally in terms of performance-price ratio.
I am correcting the rating to a 2 after this.
