    Compact, Get's the Job Done, Don't Use 1200dpi

    Put this little scanner to good use with a goal to convert paper to digital copies for clutter cleaning, it did the job quite well. My only gripe is the 1200dpi resolution option available. Many times I would get a "Memory Full" error which wouldn't take the scan or allow me to save the file. Sometimes it would allow me to bypass by scanning the same sheet a few times until the scan took or for some magical reason it could now save. It was annoying and made my little fun project into a chore. Long story short, great little scanner for home use. Has various settings for document size, color, and resolution. I've only had the "Memory Full" error while using 1200dpi (dropping down to 600dpi no issues), all other setting variations no issues. Even scanned carbon paper and the quality comes up very legible, love it. Best feature straight plug and go, small and compact, love love love.

    Portable and Lightway

    There is one thing you're going to notice about this scanner, it is very small and extremely light. This scanner is well made, it is white with black accent and it looks very nice. On the upper right corner has the start/stop button and a power indicator light. It is very simple to use, just plug it to any laptop running Windows or Mac OS, get the drivers and you're good to go. One thing I did have to do was to download the actual drivers, plugging it in and did not do the job right out the box and this was on Windows 10. In the driver installation package you get the brothers iPrint software which is easy to use. The quality of the scanned images were excellent even in color. The scanner has a small leveler which you use to adjust the paper size up to 4A (11.5), and it also scans IDs, credit cards and business cards. You can only feed one paper at a time but it is pretty cool how the device locks the paper in place once it detects it on the feeder and it scans pretty fast. This is designed for the traveler and people who work on the go, again this device is very light, compact and simple to use. However, there are some downsides, one of them being that it needs to be plugged into a laptop for it to work. Also this scanner does not have a built in battery, WiFi or Bluetooth connectivity. Overall if you don't mind having to plug this to a laptop and scan one page at a time this will definitely get the job done and is very portable. This scanner will work with Windows, Mac and even Linux. I tried it with Chrome OS but it didn't work. In the box it comes with the scanner USB3 cable and manuals. Pros: Light weight Portability Simplicity Scanned Images Design and Built quality Cons: Must be plugging to Laptop No WiFi No Bluetooth No built in battery One Page scanning
