It is very easy to program, but it ultimately only has 5 function keys. The G Keys only take one button. For example, you can assign CTRL ALT DEL to G1, G2, and G3 to have them closer. So they don't have much significance.
What is really good is the built-in USB port. It is USB 2.0, but an additional port is always needed.

Sturdy and good, the side handles are unnecessary though. One negative aspect is that the extra keys it has, although they look perfect (the one connected with USB), are not very practical because they stand above the existing F keys and thus are useless because you can't press them...

For its price, it's the best. I bought it because I wanted a keyboard with a volume wheel. It justified my decision, it works great and the wheel is big and practical. It has had coffee, coca cola, etc. spilled on it and it doesn't notice anything. The software it has is not the best, but it does its job. The only downside for me is that it is quite bulky with the plastic parts on the right and left sticking out without any usefulness.

The image of the packaging is not good, the keyboard is fantastic, and it has a very good price for the quality it offers.
