Summary: These glasses are working perfectly. They are light weight and fit much more comfortably than the glasses that came with my tv. The original glasses are rechargeable. They never seemed to hold a charge. This meant that I could never just sit down to watch a 3D movie. I had to wait while the glasses charged. These glasses take an ordinary watch battery which is included. I will have to wait and see how long the battery lasts.
Summary: The glasses themselves function perfectly fine it's the temples being flimsy instead of being more solid that causes the need for constant adjustment since the glasses start to go cockeyed and angle up on one side and down on the other. The constant need to re-adjust breaks immersion while viewing movies and playing games.
