Query: Mistake to purchase this

I had to purchase a new set of cordless phones since my others were dying on me after a few years. I picked this up at a BJ's, as I liked the features and the form factor. Big mistake. First, the battery life is awful. But worse, there are times that in the middle of the call the phone just resets. I was on an important conference call for work and the battery died with about 10 seconds warning. The speakerphone is not loud, and sometimes I have trouble hearing when there is any background noise at all. STAY AWAY from this product. I wish I had read the reviews first...
