I have been using this one for the last few months. I’m quite happy with the speed and the quality of the scans and after fiddling with the settings a bit the process from scan to paperless-ngx ingestion via SFTP is quite smooth and quick. Of course the scanner as a mobile scanner does not have all the bells and whistles of its bigger cousins (such as a ultrasonic sensor to detect multiple pages being fed), but for my use case the ADS-1700W was the best combination of price and features.
