Given the title of the object and affirmed by the seller compatibility with roughly similar patterns in the questions / answers of the product, I thought making the right purchase. Nay! Unable to synchronize the glasses with the TV. I put 2 stars for 2 reasons: - The product is of good quality, packaging is perfect, it contains a cover and a cloth (pattern 2 stars), but the weight of these glasses is nearly double that of the original Panasonic glasses. - The seller should treat his sheets to avoid any confusion in the choice of items: Title: [...] Active 3D Glasses FOR PANASONIC-TV, [...]. Now in the description in detail, only the Samsung TV are evoked. -> Back product and buying a second original pair Panasonic.
