Problem:I have the older version of this model and it works great. Unfortunately its battery would die far too fast so we upgraded to this, which is not better. Battery life barely lasts 1 hour. And when you go from AC (plug) power into battery, forget about it. Even worse in warmer weather, you lose power. Maybe I got a defective unit but my guess is that these all seem like poor quality units without any testing at all.
Solution:
Bad review
