The fans work great and are easily adjustable using a roller wheel hidden on the back. It did great dissipating heat from my 15 inch gaming laptop. The included cord is an old style USB A, not a C which is a ding against it. My laptop only has one USB A port so if I needed it for another peripheral, this would interfere. It does have an additional USB A port on the stand, but I didn’t test to see how it works. Unfortunately, the base is narrow, thin plastic and couldn’t hold up to light use. I’ve only used this for about 15 hours total across 3 months, and the plastic base has snapped rendering it useless. I only bought this to use on soft fabric surfaces like my bed or recliner. I guess the uneven surface put too much strain on the flimsy base and broke it.
