I found the people at petoi willing and anxious to help and accommodate. I have difficulty using and calibrating and I find the instructions difficult to follow.
I am currently trying to navigate the different activities available and intend to follow up with many more future purchases. I have to do more practicing and I may have further comments

So hard to build but very fun to build and fun to prank people

I recently upgraded Nybble with the BiBoard, and it is an excellent upgrade. I did have to do some modifications to the frame to mount the board so the USB port is accessible. It is more convenient not having to use dongles for Bluetooth, USB, and voice. And the expanded memory allows for the gyro to be active while using the ultrasonic or voice modes. Also can just switch modes without having to edit and compile as with the Nyboard. Well worth the effort and cost.

Bittle X is well made and sturdy and has a powerful open-source software behind it which was one of the first reasons I decided to purchase it. The capability and quality you get with Bittle far exceeds its price and we have been very happy with our purchase. Most importantly, Petoi support has been greatly responsive which has been invaluable. Highly recommend!

Great products, outstanding support! Bought the Bittle X and have been very happy with the build quality of the robot. The open-source software behind it amazing and the team supporting it even better.

I like the product very much. I also like the philosophy and dedication of the team to make everything open-source. This enabled me to use Bittle in a custom way and build many things with it. Currently, I am using it for a research project, and things are going very well. The Petoi team is very responsive to my questions and provides me with great support. I highly recommend their product.

It is very fun

This is my new favorite thing! It's incredibly easy to program in new commands and make additions to Bittle X. Support is fast - and most issues take mere minutes to resolve - for example support helped me integrate the voice module reset command into the phone app, so that I can reset the voice module in a few seconds from my phone, which makes switching between languages a breeze! This bot can withstand an incredible amount of force and is very sturdy. It's incredibly cute, and a huge hit at my workplace, since the machine learning capabilities allow it to interact with everyone, learn their voices, and act autonomously. Very easy to assemble and disassemble! This is one of my favorite purchases this year.

Supportive team. Mr. Li gave us time several times to fix calibration and other setup issues. My son learned a lot.
Great product and supportive team.

This is a mini robot dog equipped with various sensors. It brings lots of fun for kids to learn the basics of robotics control and programming. It is extensible and new tricks can be programed. Great values and very friendly support.

I love my bittle X and creator is fantastic and support is fantastic

This robot cat is unique in that it is constructed of wood. Assembled without issues, and there is a large amount of on-line documentation that is very helpful. When you get it wandering around with additional coding, it really is a cute “cat” and the included instincts are good simulations. I am impressed by the responsiveness of Petoi tech support, with e-mails answered the same day and thorough assistance including video calls. I was not previously familiar with Petoi but Nybble looked very promising so figured I would take a chance. Glad I did.

Love this

Order completed quickly. Bittle X Robot Dog is a super deal, both for education and entertainment.

Great product I’ve bought 2 of them one for myself and one for my grandson
