If you have a gaming laptop, it is a must-have. Good, large, and sturdy construction. It provides enough extra height that can strain your hands. It has 4 fans and two speeds. It has an extra USB port and the option of tilting or not. The connection cable protrudes about 4cm from the left. Make sure you have a port available on the left because the power cable does not reach the right side of the laptop.
At full speed, it has sufficient airflow and makes a discreet noise. The HP Omen 15.6" sits perfectly on the base with plenty of room, and while playing Warzone, it lowers the temperature by about 4-6 degrees. I also tried the HP Omen 17", which barely fits within the limits of the base.
Update 1: To achieve satisfactory results, the cooling arrangement on your laptop is important. For example, when tested with an MSI laptop where the air intake is in the center of the laptop (in contrast to the HP Omen, which is from edge to edge), it did not yield satisfactory results. In this case, it is better to prefer bases with fans in the center.
Update 2: As of 9/23, it still works perfectly. Only the power switch has loosened a bit. 2 years of intensive use for gaming and work. During the summer, while playing Warzone, it lowered the laptop temperature from 86 to 79-80.
