Query: TERRIBLE VIVSION

HOW TERRIBLE QUALITY! IT IS INVISIBLE, THE PICTURE KEEP ON SHAKING, YOU CAN¡T SEE A STRAIGHT LINE FROM THE TELEVISION. THE COLOR SHOWED IS NOT SHARP.THIS IS A PRODUCTS FOR BABY LEARNING LANGUAGE. I THOUGHT THIS MUST A GOOD MATERIAL FOR MY BABY WHEN I BOUGHT. MY BABY AND I WATCHED THIS TAPE TOGETHER ONCE RECEIVED THE PACKAGE. I FOUND THAT THE VISUAL IS SO BAD. IT IS NOT SUITABLE FOR ANYONE. IT WILL HURT YOUR EYES. MY BABY AGED 21 MONTHS ONLY. HE IS IN A VISUAL DEVELOPING STAGE. I STOP TO LET HIM WATCH AROUND 10 MINIUTES RUNNING.ACTUALLY, THE CONTENT OF THIS PRODUCT IS VERY GOOD. IT IS AN EASY WAY FOR LEARNING. HOW CAN A MOTHER TO LET THE MATERIAL TO HURT HIS SON¡S VISUAL DEVELOPING? I WILL NOT LET MY BABY TO USE IT.
