Excellent reader with really good support
Excellent machine, simple and effective, well made with full instructions and easy to use. When I had a problem (my fault) I got rapid and correct technical advice to correct it. Sufficiently satisfied that I've bought a second one.

Helps with quicker data entery (QR Codes and Barcode)
Not being used for its original intention, but has proved useful when doing a kinda 'data entry' task, in short I have templates of a 2D Design and I wanted to put students names on (mail merge doesn't work here) so created excel with list of names (and other info) had it auto create QR Codes, open the template, edit text box, scan code info added, save/close open next file etc. Cost is really good, instructions are fairly easy, used a USB Dongle rather than Bluetooth. Scan 95% of the time (sometimes aiming is off and it scans the wrong QR, (so I go with showing one at a time). The only downside is job every so often, it's easier to clear settings, reconnect to get the device working after an extended time of not being used (IT-Turn it on and off situation). Happy with end product

Does NOT work with Square
So, it is a very very useful product. Quickly connects to windows. Comes with a 2.4GHz usb reciever as well as a cable. The only issue 8 have with it is that I actually bought it to use with square... that is my own fault as it does actually state on one of the pictures that it does not. I missed that so if you are looking to use it with square, you may need to look elsewhere.

Beep failure
It is a great and easy to use Barcode scanner. However after 30 days of purchase with not very much use the audio Beep has failed, which isn't very helpful when you need to know if an item has been scanned and entered onto the software we use. If anyone could help with this I would be grateful. We have used the barcodes supplied with the scanner to try and rectify the issue but so far that has not worked.

Works as well as wired ones!
Needed a wireless scanner for scanning the barcodes into the system but didn't want to have more leads over the desk. This is perfect. Plug in the usb dongle, and away you go. Simple, easy and no wires!

What a fantastic product, truly a price-performance beast!
I dropped it from a height of 1.50m on the very first day, and nothing happened. It has an amazing reading laser and is extremely comfortable to use. With competitor brands, this product would cost at least £100. I absolutely love it! Once I complete my tests, I will purchase these for all my office staff. I am a happy customer, and I am writing this review purely from my own experience. I specifically want to mention this because people hardly trust anything these days! Thank you!

Such a time saver
Such a time saver, I have a SKU system for the storage of my stock. This helps when listing stock. I can scan the barcode for the location and it saves SOOOOOOO much time. I have used it for the QR codes too, to keep stock of serial keys that come as QR codes.

Annoying connection
At first it was fine and doing what igs made for . But now I am having quite a frustrating problem. While using the Bluetooth mode it. When it turns off automatically and then I turn it back on . It does not reconnect automatically. I'm forced to take the USB dangle in out again for it to reconnect

Shopify Compatibility
It works as it should, the instructions are kind of iffy but looking it up helps. This does work with Shopify! Much cheaper than the other options. I used it for a day or so plugged into the iPad base and then it stopped working. I bought a dongle and plugged the small dongle (that wirelessly connects the scanner) into the bigger dongle. Now it works fine, I'm not sure why it randomly stopped working plugged directly into the iPad base but now it's working as it should.

Simple et efficace
Bonne qualité de construction, notice plutot bien faite. Seul bémol, le paramétrage fonctionne bien, mais lors de l'essais avec les codes barres représentant les lettres cela ne fonctione pas. Alors que la scanette fonctionne parfaitement. Essayer avec d'autre codes barres (avec ou sans lettre) et dans excel ou bloc note il n'y a aucun soucis. Elle marche bien.

Ottimo, reattico e comodo
La prima cosa che salta all'occhio è la velocità di lettura, comoda la possibilità di utilizzarlo in WiFi, istruzioni e settaggio ANCHE IN ITALIANO, e non è cosa da poco, anche perché sono impostabili tramite i QR inseriti nella stessa.

Perfect upgrade for our retail checkout lane—with stellar battery life!
Our old barcode scanner was constantly lagging and missing scans during busy store rushes, so we upgraded to this wireless Tera unit. It has been a total game-changer for our checkout counter.The scanner picks up standard 1D barcodes instantly, but where it really shines is reading 2D QR codes directly off customers' smartphone screens for loyalty apps or digital coupons. Anyone in retail knows how frustrating it is when a scanner won't read a glossy screen, but this one catches it on the first try.The wireless range is excellent as well. I can walk out from behind the cash wrap to scan bulky inventory items still sitting in a customer’s shopping cart without losing the signal. On top of that, the battery life is absolutely stellar. It easily powers through multiple busy shifts back-to-back without needing a recharge, which is a lifesaver when the store gets packed. It feels comfortable in the hand, has survived a couple of accidental counter drops already, and required zero complicated software configuration to set up. Highly recommended for any small business owner!
