Gondola - Hi has anyone had any experiences with this device from Europe, had a trial or bought one?

Hi christmas
Did you get any feedback to your query about Gondola (Oct ’17)? As a potential user, I would be very interested to hear of any actual experiences of this device. The trials reported by its developers indicate that it can improve certain aspects of gait. However, I cannot imagine spending several thousand euros on the product without evidence from users that it can address the problem of freezing to a useful degree.
