Attention!!!! It does not come with a compatible USB A to USB A cable; you need to buy it separately. As a cooling pad, it's decent though

Very good and flexible base. The construction is satisfactory, made of good quality plastic with metal arms to lift it up, which folds and becomes almost "flat". Its weight is small so it can be easily transported. It has 5 reclining positions, is stable in all positions, and is suitable for all viewing heights. It also has a stop on the base to hold the laptop. It has peripheral lighting in 3 colors with the ability to continuously change - I disable this feature which is essentially only for appearance while consuming power. The fan is one, of large diameter with 6 speed options. I find it completely silent and it does not bother at all. The cooling is satisfactory but not top-notch. However, the surface of the base is meshed and the air passes through the bottom of the laptop even without the fan being activated. Finally, it does not take up a USB port as it has two hub outputs, which means that the laptop port used for charging the base is replaced by the free hub slot of the base. My laptop is 17.3" and it covers the entire surface from edge to edge, so I do not consider the specification for 19" to be correct as a 19" computer will protrude quite a bit - mainly in depth, reducing stability. In conclusion: a very good, stable, and functional base for laptops up to 17.3" (maybe even a bit larger) and with an unbeatable price for what it offers. I will come back if I see something worth adding.
