Review on 🐶 WOOFCAI Dog Buttons for Communication - 4 Pcs Recordable Dog Talking Buttons Set with Stickers Pet Clicker Training for Dogs Speaking Interactive Tool Answer Buzzers Buttons by Samantha Allen

Batteries not included so I had to look for it. The battery compartment is difficult to open. Once the batteries are in, press and hold the record button. I tried recording multiple times on each key. They're clear enough to understand what they're talking about, but not as crystal clear as previous knobs I've bought. The price is good, it comes with stickers and some blank stickers to attach your sound. My dog picks up words/buttons fairly quickly and it's great to have this opportunity to communicate.
