After two months here are some of my observations:
I just figured out another reason why this is not called a wheelchair. While the arms do fold back, they do not fold back enough for one to do a side transfer. I do not think that someone who has no use of their legs could use this without being lifted into the chair. I learned this the hard way one day when I was alone and having great difficulty getting up to transfer to the whill.
Standard advice is to always turn off a power device to conserve battery power. Still valid here - but there is another good reason too. It is easier to hit the control button than it is to accidentally squeeze the power tiller on an
ECV. At a restaurant I had turned it back on getting ready to leave. I leaned over to pick up my purse and took out the table - which fortunately was now empty. But recently at home I left it on as I transferred as I was sitting back on the Whill I'd left clothes on the arm which I jostled. The Whill went backwards as I was sitting down, and I do not know how I did not land in the floor. Close call.
The battery power is displayed very prominently and very accurately on the arm of the Whill. My ECV had lights that were absolutely not reliable at all. I never really knew how much power I had left. The Whill says 100% when fully charged and then shows the exact current amount at all times. I love really knowing what my battery status is vs an approximation.
It really charges quickly. From zero charge (which I've never gotten down to) it is estimated to take 5 hours to charge. I usually charge when I am down to about 30% unless I have a big expedition out of the house planned (rare). One day I was charging it while watching TV but needed to use it about 45-50 minutes later so I unplugged it. I was pleasantly shocked by how much it had charged during a relatively short time period.
I've used the remote drive function more than I thought I would. Yesterday while getting my hair cut I transferred to the operator's chair and then moved my Whill out of her way. When I charged it by myself I transferred to a chair and used my phone to turn the Whill around so I could access the back.
The Whill can be locked via the iphone or with an optional key fob. I haven't done that as I rarely leave the chair when out in public. And even then like at the hair salon it was only a few feet away from me. But it's a nice feature.
