## What reviewers found

### Miko 3

- The Gadgeteer: Content was good with Max and the robot survived several 2 foot falls, but without Max the library was thin and the conversational AI was slow and often could not answer. Reviewer said it feels like a pricey tablet. [Source](https://the-gadgeteer.com/2025/03/27/miko-3-the-ai-powered-learning-robot-review-a-small-tablet-dressed-as-a-robot/)
- Serious Insights (3): Kid friendly hardware and familiar subscription content, but laggy voice recognition, answers too advanced for young kids, slow charging and weak standby battery. [Source](https://www.seriousinsights.net/miko-3-review/)
- TTPM (4/5): Packed with stories, dances and learning missions and answered most questions well; battery lasted about 5 hours of active play and WiFi is required. [Source](https://ttpm.com/products/miko3-ai-powered-robot-for-kids/)

### 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](https://makezine.com/article/technology/robotics/petoi-programmable-robot-pets-reviewed/)
- 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.

- 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](https://www.hintonmagazine.com/post/review-exploring-the-world-of-robotics-with-petoi-robot-dog-bittle-x)
