Loona Deskmate is less a pet and more a moving desk assistant that also works as a big USB charger. It suits iPhone owners who want a friendly face on their desk that can handle email and calendar chores. Skip it if you use Android or want a robot that moves around the home.

Bittle X V2 is a strong pick for kids 10 and up, students and hobbyists who want to learn coding and robotics on a real legged robot that runs offline. Skip it if you want a hands off pet for cuddling or long play, since it walks about an hour per charge and the best experience involves some programming.

What reviewers found
KEYi Tech Loona Deskmate
- CNX Software: Crowdfunding preview, not a hands on test. Reported three near silent brushless servos, three USB C and one USB A port, about 0.5 second voice response claimed by KEYi, and paid credits for advanced tasks such as deep research. Source
Petoi Bittle X V2
- Make:: Tested the Bittle X V2 with arm alongside the Nybble Q; noted built in voice control and an ESP32 board, that you never have to assemble circuit boards, and that Bittle is the more durable choice, though neither is a foolproof consumer product. Source
- Movies Games and Tech: Pre built Bittle X ran about an hour per charge; 35+ voice commands were new for this edition; setup needs software on a computer and the box has no printed instructions. Source
- Hinton Magazine: Praised the DIY kit as a way to learn robotics and wiring, the durable interlocking parts, OpenCat programming and 35+ voice commands. Source
