Total Recall met all expectations of what I would be using it for when it arrived. I use it to record notes while driving for later use, and in meetings to review in detail those items that may not have been noted with the conventional pad and pen. The 90 minute time limit should be able to last through most meetings. The stand alone unit is small and fits into a pocket easily, and will detach and insert into the Visor readily, notations about content can be attached to "tracks" when in the Visor. I have tried using the Total Recall with only the built-in mic for recording music at a concert, and must say, it recorded the sounds, but this type of recording is better left to an MP3 type unit. I view my purchase of the Total Recall as a sound investment for my intended use.
