It does what it's supposed to do. After two months of use, I have no issues at all. You simply plug it into a USB and it's ready to go.

I can confidently say that after several days of use, it has left me quite satisfied. It concerns a courier company and it works flawlessly with all kinds of barcodes, even through a mobile phone or computer screen. Excellent purchase.

Very good with all QR codes, it is plug n play and very user-friendly. However, it does not recognize very large barcodes (e.g. ENFIA certificate codes) because it has a small field of view. For simple barcodes and QR codes, it works great.

There is nothing, you simply plug it into the USB, open a notepad, excel or something similar, and it scans whatever you want. It might be a bit bulky, but I haven't seen any other scanners.

I read a comment about another scanner that if it has many QR codes, it reads them incorrectly, and this applies to all scanners. That's why you see in pharmacies, they put a piece of paper over the QR code that they don't want to scan. There is no other way since the beam is huge in range. Or you cover it with your finger, the one you don't want to scan.
