Momo Tabari | January 2024
"Alienware’s m16 R2 is a solid gaming laptop that leaves much to be desired, particularly in its quest to fulfill your needs as a product for productivity. Battery life under eight hours and a dim display are both vital issues for something that will accompany you through school projects or a workday. However, the Alienware m16 R2 is an exceedingly powerful gaming laptop, consistently being one of the best in our performance tests when compared against similar products. Even then, its display is lacking color, its fans get pretty darn loud, and its speakers aren’t punchy enough to rise above that noise."

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
