High powered. I used at my sumo robot 6 part of it with small 4.5cm wheels. They don't draw very high currents but very powerful

I used them at my competition without any problem. Please also print 3d covers for extra protection to other beams. Good fit with Microstart remote. Thank you JSumo for sponsoring us.

We had won 2nd place with this robot's design. We custom made code and it was fast to code, develop. I wish we had more room for battery.

In my opinin best mini sumo robot kit with easy to assemble. I made assembly by this: http://blog.jsumo.com/how-to-assemble-m1-mini-sumo-robot/ What can I say bout kit? Pros: Powerful Ready codes Good silicone wheels Metal parts no plastic or adheshive needed Cons QTR1A placement. Overall it is very good kit with compered price to higher end models.

Arived to us in 1 week. Thank you for extra blades.

I received with careful packaging. Assembly was easy. At coding please install version 3.0 library not 4.0 that was my fault.

I oredered and arrived to me in 3 days. I liked it's flat side. It grips to surface very well but also needs good cleaning (as usual). I will contiune to order other wheels models too.

Best sumo robot wheels, ever!

I amazed of body kit. Very easy to assemble and everything suits very well.

It steps further. Without ebook lots of knowledges would not known or leant with lots of experinces.
