Super Sphere STEM Experiment Kit

For $100 I expected better quality, design and ease of use. DO NOT BUY OR WASTE YOUR MONEY! We have not been able to connect the (very poorly rated app) to the device. I wish I would have read the reviews on the suggested app for this product, I would have stayed away. Instead I went by the review here (which *includes* ratings from other products, buyer beware! It does not reflect reviews of the sphere!) We did all the troubleshooting. We tried different devices. Tried the one recommended in the answers here AND the different app recommended in the manual. One of the trouble shooting tasks is to turn off the machine's Bluetooth to reset it. Cool, easy right? They did not make an on/off switch (?!) so you need to dismantle the machine to take out the batteries....because the batteries are not accessible either. Without the app to program or move it, its just a cheap plastic breakable sphere with no purpose. Wildly overpriced, and a waste. Run away and spend your money on better quality sets.
