Avid chips are common in my area and a lot of rescues are using cheap, inexpensive scanners that do not pick up in them. In less than a week, a dog was returned to its owner because it was rescanned with this scanner.

I received the microchip reader very quickly, CPS was amazing to order from! I haven't had the chance to try the reader out in the field yet, but I turned it right on and tested it on my 4 cats and the chip number came right up and transferred easily via Bluetooth to my notes on my iPhone. It's nice and portable and comes with a wrist strap, and a small carabiner on the pouch to clip it on to something if you wish, as well as the chip tester and easy to use instructions! It would be even a bit better if it had some sort or grip material on the sides and back, it's a bit slippery in my hand, but I will be adding a bit of that on myself.

All in all, I like it.

I bought this model over a number of others because of Countryside"s great price, & because it can scan pretty much everything current. I could have gotten a cheaper model that would scan just the chips I'm using, but thought, well, what if I switch chip brands, or buy a dog with a different chip, or something?

It scans very easily. The display is a pleasant blue, & is bright enough, with numbers large enough, to read easily. And, it not only has an auto shut off, in case you forget, but uses a common 9 volt battery. not a hard to find one, or a bunch of AA or AAA's you never have enough of, when you need them.

The bluetooth function sounds great, & allows you to pair to your bluetooth devices, & save the scanned number, but you can only save the number while it is displayed. I wish it had some storage capability, and it does require a text editor, like notepad at the very least, to transfer the data to, which is great for Windows, but isn't native on Android, so you'll have take time searching for & downloading one you like, to save the up to 15 digit codes. So that feature doesn't necessarily work right out of the box. Still, it was a minor inconvenience.

The other thing is, it is a hit bulky, in the way a really old calculator is a bit bulky. You would think it would be "pocket sized" at least, now days. But it should fit most people's hands.
Also on the plus side, the nice pouch, with test chip key fob. I chose black, but the lime green one would be hard to misplace.

BTW, I actually called Hero's customer service with some initial questions, and they were very pleasant, & helpful, & in the days of Covid, didn't leave me on hold for half an hour before answering!!!

I was looking for easy to use quality reader i found it and price was right highly recommend this unit

I am very happy with this little device. I have tried it on a few different chip types and have always gotten a read. What I really love is that it reads from a little bit of a distance from the animal!
