They have a Tesla Bio Healing place in Tampa, that I took my brother to after his stroke. He basically only said yes, no or giggled when you asked him something. He was there for 3 days, other brother was with him, but he didn't really "sleep" like you were supposed to. Bro that had the stroke slept for the 8 hours each day and by day 3, he was actually talking and made a complete 180. Cost me around 1800 bucks but I didn't care. It REALLY helped him and he got better every day after that. They also sell their units. The largest one is like 11K, personal use one is like 500 but they also have BOGO deals. I'm waiting for them to go BOGO then I can get 2 of them
