Review on Efficient Alacrity 2D QR Bluetooth Barcode Scanner: Hands-Free Reader for Industry, Retail, Logistics, Warehouse with 2.4GHz Wireless & Wired USB 3-in-1 Connectivity and Stand by Todd Adams

I don't like giving negative reviews, but it really annoys me. I know other Bluetooth barcode scanners. No matter what I do, this scanner will not go into Bluetooth pairing mode. None of the methods in the guide work. After charging and unplugging the charging cable, I tried unsuccessfully to turn on the scan switch and hold it for 8 seconds. I then used the barcode method, went into setup mode, selected BT HID, went into pairing mode and it just wouldn't go into pairing mode. The blue lights flash briefly, but the device is not visible. It pairs with the included Wi-Fi dongle, but it's useless for a smartphone. I'm afraid I'll have to return this if it can't be resolved.
