Sascha Mölck, | April 2022
"The Asus VivoBook 15 is a quiet office notebook with a strong screen. However, the VivoBook 15 still has room for improvement. Office and internet applications as well as simple games do not pose any major challenges for the VivoBook - this is ensured by the built-in combination of Ryzen 7 5700U APU and 16 GB of RAM. Heat and noise emissions are acceptable. But, the laptop has weaknesses that should not be present at this level: lack of keyboard lighting, a slow memory card reader, no fast USB-C port (USB 3.2 Gen 2 or Thunderbolt 4) with Power Delivery and DisplayPort. Battery runtimes can only be described as average."

Mark Knapp | January 2023
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Plus, those alternatives are much more enjoyable after work."
