Doesnt work consistently

It only responds about 25% of the time. Ive tried all manner of tones to my voice and volume levels.

Also, note that you wont hear it if a headsets plugged in - IOW, if you frequently set it down after youve been listening to music, you wont hear the Polo response because itll be feeding thru the earbuds.

The developer should have provided a free trial period....
