    Other units I have, exact same type function as intended. I took away one star. Not because of the unit, but because of the price. Issue is that BB was charging a higher price than what another local store was selling to for during the BF sales. A dollar or so more okay, but much more than that and I have to questions why there is a difference or why it is that a pricematch was not offered to begin with. Price matching was a no-go. exactly same unit, stock number, etc.. BB should at least price match it.
