Purchased from a well-advertised store in Ilioupoli (I won't mention the name to avoid advertising), after the third use, the on-off switch stopped working. Result: no PC. The store requires "due to COVID-19" 15 days for inspection and return, with back and forth transportation costing 5 euros. No work for 15 days and wasted money on a defective product. GARBAGE (to avoid any misunderstanding, I am not referring to the store but to the product). 1 star due to system requirement. It should have been much lower
