## What reviewers found

### Casio Moflin

- The Verge: After weeks of use the reviewer found the motor whir and constant reactions to every sound irritating, called the app thin and ended up using Deep Sleep Mode to silence it. [Source](https://www.theverge.com/gadgets/877858/life-with-casio-moflin-robot-ai-pet)
- Tech Advisor: Needs to recharge about every five hours, has audible neck gears and limited movement; a soothing conversation starter, but the bond felt one sided for the price. [Source](https://www.techadvisor.com/article/3086689/my-ai-pet-moflin-made-me-take-him-out-to-dinner.html)
- Fast Company: After close to three weeks the reviewer grew attached and called it one of the first AI companions that is actually useful, despite chirps interrupting a video call. [Source](https://www.fastcompany.com/91431412/casio-moflin-ai-pet-review)

### Unitree Go2

- New Atlas: Go2 Pro handled curbs and uneven ground and offered ChatGPT voice commands, but needed a flat surface to start, once fell down front steps, struggled to start on grass or sand, and its purpose beyond novelty was unclear; got 1 to 2 hours per charge. [Source](https://newatlas.com/robotics/review-unitree-go2-pro-quadruped-robot/)
- Fauxhammer (4/5): Impressive movement and terrain handling with useful lidar mapping, about 2 hours of battery, but inconsistent voice recognition, overcautious obstacle avoidance and limited practical use. [Source](https://www.fauxhammer.com/reviews/unitree-go-2-pro-review-whats-the-point-of-a-robot-dog-really/)
- iFixit: Teardown found a hand removable battery built from standard 18650 cells and separately connected motors, but parts are sold only by contact form and stair testing cracked the neck.
