Review: Works great for me - I used this as a replacement for the original in a Studio 1 and it worked great. The screwdriver that comes with it will only open the battery box [normal Philips head] so you will need a star type driver to open up the speaker itself.
Review: The item was charged and in proper working conditions. - The battery worked immediately as soon as i put it in. Working as intended.
