My Mom is using this product. Recommended by the Canadian Institute of the Blind.
It’s not perfect. Battery life is surprisingly short.
She doesn’t think she’ll use it all that often.
It’s expensive, too. Right now USD $700 or more. But there are similar less expensive competitors available.
I saw one as low as USD $18.
