## 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)

### Sony aibo ERS-1000

- Engadget: Impressive sensors and cloud AI, but setup and the mobile app were slow, it struggled with floor transitions, its servos were loud at night and it took about two weeks to show personality. Concluded a shelter dog is a better choice for most people. [Source](https://www.engadget.com/2019-02-27-sony-aibo-review-just-get-a-puppy.html)
- Tom's Guide: Adorable and fun with a personality that grows, but the reviewer got about 1 hour 10 minutes of continuous activity, the app was sluggish and it often ignored commands during training. [Source](https://www.tomsguide.com/us/sony-aibo,review-6349.html)
