## Questions buyers ask

### Should I buy the kit or the pre assembled version?

The kit costs $20 less and takes about 40 to 90 minutes to build per Petoi. Pre assembled adds a remote and is ready to play.

### Does it need WiFi or an account?

No. Petoi says voice commands are processed on the robot, and the app connects directly to it.

### Do I need the alloy servos?

Only for the robotic arm or heavier use. Petoi says lite servos cannot support the gripper.
