few folks on forums have them.

can't see you'll get long term experience since only been on the market
a short while.

realistly I suspect durablity and performace would be good, which is

the issues I suspect is less durablity, but rapid obsolescence.

clearly batteries will not like being stored in cold sheds etc.
