This barcode scanner has a ton of features and does the job easily, holds a charge and charges quickly.. Big or little jobs, this barcode scanner is can keep up with any task. My brother recently started a small business, so I use it there to help him during inventory time. I proved to be highly accurate, is light weight and easily adaptable for my small job to big warehouse jobs. I would definitely by more for more demanding jobs, well worth it.

This isn't like your regular barcode scanners that just scan and work. You will need to use an app (pretty much all of which cost money) or develop your own. For the $370 cost, I'd expect more. One of these days I'll figure out how to actually use this, but until then I've been using the old school scanners.

This scanner has made managing inventory much more efficient and has really sped up the inventory process. The scanner has a built in keyboard and allows for quick data entry. The scanner has a rugged design with waterproof rating so it should be very durable in the long run and last a long time.

It even comes with a screen protector. It's an Android system, and the display effect is not bad, but the brightness is not enough. I'm not a professional courier, but it can check QR codes and one-code passes very quickly, but it only displays numbers or some garbled characters. I don't know what it is used for. If you use it as a mobile phone for the elderly like me, I don't think it is suitable. The lock screen can only support password input, and does not support finger or face recognition, but it supports Chinese, which is very good, but it does not support Chinese input method. If you use it as an mp3 connected to a speaker to play music, you will find that there are no buttons on both sides to adjust the volume, so I won't say more. In summary: if you are not a professional, I don't think this phone is suitable for you.
