Universal Pet Microchip, 134.2kHz ISO11784/5 FDX-B Pet ID Tags, 15 Bit RFID Microchip Implant Kit for The Management and Tracking of Animals (20PCS 1.4 * 8MM)

I love these they're easy to use

Great choice

These are easy to use and keep track of animals with.

These are great!

I have had other brands of chips with needles for dogs, and they are hard to put in. Thank goodness these are high quality actually very sharp needles and one per each chip!! Others give you 10 chips and one needle, that is not going to work good at all! Pleased with this brand !

As a breeder and Vet Tech I Have used 100+ of these microchips so far this year. They are easy to place and every universal scanner we have tried have picked them up quickly.

Great product

Disclaimer, I bought these for the chips only. I am trying to make custom Kyber crystals for my Galaxies Edge Disney Lightsaber, and as some gifts to friends. I came to these from a Reddit link claiming that they worked. Spoiler alert, this Amazon listing is for ONLY 134.2kHz. Which does not work. Despite there being some information in the listing that says 125kHz, these will not work with any of Disney’s RFID driven tech. So if that’s the reason you’re here, keep looking. I found some on aliexpress that might work, and have ordered them. I will update this response when they arrive and I know if they work or not. Other than that issue, the item seems like it would be fine for microchipping pets. The needles are very sharp, each syringe comes packed in its own sealed packaging (I assume sterilized) and there is a little nib in the needle cap to keep the chip in place right up to the point where you open it and inject the pet. So if that’s the reason you’re here, I guess these will work fine for you.

the end near the needle is broken, it is not that strong. Fortunately, the veterinarian found a way to put it on the cat. I didn't return it because I needed to use it on my cat because 3 days only I was going to bring my cat home to our country.

As i check the microchips with microchip scanner/reader, the 4th number is missing while i checked the barcode with barcode scanner, the numbers are complete. Ex.: Numbers on- Microchip Scanner: 900 22060203657 Barcode Scanner: 900022060203657 Your kind assistance to correct this issue. Thank you very much

This was easy to use. Comfortable to hold.

I bought these for my puppies and they are accepted by CkC
