My mother needed a device to help her with speech after her stroke. I ordered the advice which was hard to find online. I informed speech therapy of the price that they charged. I was told it was twice as much as I should have been and was not a complete unit. They were piecing the contents of the box out. Luckily it was out of stock and I was able to cancel my order.
Tip for consumers: They give you no access to stop notifications. I had to pretend to be ordering something to be able to talk with someone who said that they would take me off their email list. They are harder to get rid of than lice in my opinion.
