Color Identifier-Light Detector - Spanish

I bought this item for my 93 yr old Mother to differentiate colors while dressing. We tried every option to get it to operate correctly, eight out of 10 times the color was incorrectly identified. My Mother is blind, she needs a reliable identifier.I returned the item without any problems.

My wife likes it but it has some difficulty with purples especially on the blue end which it identifies as Blue. I think the voice could be improved (English).
