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."

Andreas Osthoff | April 2023
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
