Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

Example Input: This was actually the wrong product for me, but the customer service was so outstanding I want to give it a 5 stars anyway.We already have an Ayrstone hub that works great for us (and have received great service for that as well).<br /><br />My father owns a hotel and ordered this thinking it was a repeater. I did not get home to set it up until months later to set it up and realized it was the wrong thing. At first we decided to keep it anyway to use with a different hub we already own as was not good enough by itself as a repeater. The Ayrstone team did a great job helping me decide whether to keep it or not, explaining the setups needed, and then took it back for a full refund after we realized we could not really use it after all.<br /><br />I am going to get a second Ayrstone hub in its place as a repeater. More expensive than the repeater we already have, but the original hub works so well we are going to get another.

Example Input: The battery is doing great! My old mac battery pretty much blew up out of its shell and no longer sat in the charge component so I had to keep it plugged into an outlet all the time to keep the computer from dying. It's so nice to have a good battery again!
