Horrifying to be brief! Service and support are incredibly poor. I actually called the wrong company by accident, and they trashed SonoHealth. That's pretty bad! I can't get the unit to work. I've been using it for a few weeks and then it went kaput. Spent about 1 hour yesterday (1-20-22) with someone and he was unable to help. Told me he'd have someone call me back...still wait. Garbage product! Can I assign a negative "star" review? I communicated by phone and email. Below it only allows one option. Question # 2 N/A because I called an spoke to someone immediately.
