I haven’t used a scanner for a long time . the last one was which warmed up for 5 seconds. 10 years later, almost nothing has changed. only warming up became almost imperceptible. But it still fidgets before scanning and each time the nonsense returns to the starting point - and could scan the next page on return. Probably you have to pay for it separately. Pros below: inexpensive, popular you won't find better in this budget tolerable scan speed no separate charger required expected reliability, brand Different cons: looks cheaper squeaks the lid could open across instead of lengthwise thick and empty you need to install drivers for the buttons to work
