Great quality and fast shipping — very satisfied Review: Revived our sound machine - We love a sound machine we bought from Brookstone several years ago. As life has it, technology turns over at an alarming rate these days and replacement parts - even something as common as batteries - become unavailable. Our sound machine used a slightly smaller battery with a slightly different plug. But with a little soldering and heat shrink tubing [two wires; one red and one black], this new battery fit perfectly into its designated space. It's a perfect repair for our beloved machine. It's quality of sound for its size plus the types of sounds it creates is our favorite features and we are thrilled to have it working once again [the old battery swelled warping the internal mechanisms]. Sleep is important and with our sound machine we get really high quality sleep. Repairing is always preferable for us over replacing and with this solution we are quite happy. Now, I've got to turn on our machine and go take a nap [yawn]. Don't let the difference in connectors shy you away. With a little ingenuity, you too can repair something. Plus you probably have a friend who could help you out if you cannot do this yourself anyway. Give this a shot. We did and we're glad we did. ## Features - Make Sure Device Polarity Matches with Battery Pack Connector Before Purchase!!!-1.Battery Size; 2.Connector Model; 3.Connector Size; 4.Connector Polarity - This is not universal!!!
