Tyrone, Good! They are not a sponsor. Once they were and back then is when both of us got ours after a lot of studying. Comparing them to all, they are still our favorites. I am sure a lot of others work, even acceptably for many, but, we are very glad we have these. The features seem to be better, at least to us. I wish they were a buck and a half, then everyone would have one. Be a good thing.
