Well I have had one of these since April, and not seen any real comments on them.
Battery, is good or better than its word of 8 Hours, with an audible warning of say an hour that battery is low, but just because the warning stops, and the unit still functions doesn't mean the battery is all better again, its a case of saving power as its about to die, so stop warning provide air ( nice concept)
Takes a bit of adjusting for fit, and those with glasses, take a bit of manoeuvring to get it on, and off.
The motor is at the back of the unit but the noise from it is acceptable to the ear, but please remove hearing aids if you wear them, that could make it deafening
I have had a couple of bugs with the one I purchased
The front head band has a foam wrapping which fell off almost as soon as it was out the box, better double sided tape fixed that
The head covering is press studded to the face shield, but uses plastic press studs. In my case as I was removing the covering one of the studs completely detached, I believe this was down to the stress induced y the material between studs being stretchy
Speaking to the manufacturer about the issues, resulted in FREE replacements arriving next morning in the post, so hats off to them on that. And they will be looking at improvements.
They are also looking at an external charger for those that want that backup supply.
The only issue I have with the unit is weight, and I will stress that this is due to a neck injury I incurred over 25 years ago. As the battery is above the head , it adds weight. When turning it is unlikely that the user will keep their body and head vertical , which causes the weight to be forward of vertical putting strain on the back of the neck. Maybe for me I need a counterbalance lower down. But in the meantime, a simpler solution is a coffee break every hour
