Review on Programmable App-Enabled Robot Ball For Kids Ages 8 & Up - STEM Educational Toy By Sphero Mini (Red)! by Chris Pollreisz

I use this primarily as a cat toy, and would recommend after my experiences. Some performance observations:• The orientation calibration gets lost every 10 mins or so. Due to my high latitude, I have 50μT magnitude magnetic field strength but only 20μT parallel to the ground; Maybe that's why it has trouble.• When driving on a hardwood floor, the slightest impact will make it go into an erratic tailspin. A little more traction by the ball or some software to limit/filter the acceleration would help.• The shell splits open occasionally, but not a big deal.• Battery life and customization settings are good.• If you're cat is skiddish or afraid of a Roomba, it probably won't like this as a toy.
