Moflin is a quiet hand held comfort pet for adults who want something to stroke and hold, and it is the most private option here with no camera and on device AI. Reviewers split sharply: some grew attached, others found its motor whir and constant reactions irritating. Skip it if you want a robot that moves, talks or plays, because it only wiggles and chirps.

aibo is the most lifelike robot dog you can buy in the US, with real legs, a personality that grows over years and Sony's support behind it. It is for devoted fans and households that can absorb a $3,200 final sale price plus $300 a year after the third year. Everyone else, especially families wanting a durable toy for kids, should skip it.

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
- 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
- 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
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
- 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
