GRANDSON USING THIS IN COLLEGE! HE SAID IT SAVES HIM SO MUCH TIME!!!!!!!

I got this Btopllc Voice Recorder 8GB Voice Recorder Lecture /Conversations - black for my grandson that started college this year and I knew this would come in handy for him with all the papers he is going to have to write and his lessons. This has a one-touch recording and high-quality recording, 3 recording modes, VAR/VOR system (Voice activated and operated recording), recording via high-grade built-in microphone, records telephone calls, records with the external mic, LCD screen with color backlight, free drive USB flash disk, built-in lithium battery, low battery indication, has a time stamp, displays hours and minutes. Best of all this comes with a one year warranty. He loves this recorder, he said it has saved him so much time in his studies and is easier to do his lessons now, cause he uses it in class to record when the professors do their lessons.
