I had 2 pairs battery with my TV but the batteries go at full speed, not to mention the discomfort of the original glasses.
Of course you are not going to buy 1 rechargeable pairs for each family member, but it's always nice to have one.
First is infinitely superior comfort, there is no longer the boss in the nose. A minute charge and you are quiet for your movie, they are light
Level picture I did not notice any difference. Pairing with the TV works the same way.
