Sascha Mölck | November 2022
"The Acer Aspire 5 15 is a good value office laptop with reasonable battery life. The combination of slim exterior, relatively low weight (approx. 1.7 kg) and 8 hour real-life battery runtime makes the Acer Aspire a truly mobile laptop. The modest Tiger Lake processor supports this area and simultaneously ensures an affordable price point. The Aspire produces little noise and stays cool. The screen (FHD, IPS) might not win any prizes but is entirely appropriate for the price."

Allen Ngo | May 2021
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
