I liked the design and steel construction. Very durable. All parts arrived to me complete. Bearings was attached readily to body.

I am using them for my mini sumo robot. I also used Pololu and fingertech series too but this have good torque and speed. Also shipment to Romania was very quick just faced a delay at cargo office (Shame on DHL)

I ordered for sumo robot. Works well as expected.

I hope you can manufacture 4mm hole models for 25mm pololu motors.

Very flat and soft. I am using wet towel for cleaning. My only recommendation to new buyers is add extra spare wheels too. And make cleaning well.

I likes the ease of assembly. I wish JSumo can add seperate body parts too.

Best value for competitions. Suggested. Also Mr. Firat helped us too much, especially thanks to him.

Came to me assembled. Very powerful and easy to disassemble (I will disassemble for more modifications)

A good starting point for beginners, I will order more for my other students. The most difficult part was adjusting the sensor height. (5-6mm is enough)

It can see mini sumos from up to 60cm. And it can sense black objects very well.
