I find this as a great invention! No more Bluetooth problems when trying to connect the speakers with a phone or another device. I especially like the solar powered feature, so we can use it as long as we want to. I hope the solar charger is strong enough for effective and fully charging. This device also has a touchscreen! Congrats for finding this great product! I will write it on my "check it out" list :) Have a nice day! :)
