but a set of spare keys would be very useful in keeping it spotless
much better as the keys are easily removeable
just bag the keys up and pop-into the laundary system

I've been using rechargeable batteries which works fine for me
my sister who got hers along with her partner both use fresh batteries
which I consider a bit of a sin since it's cheaper to use rechargeables

the base plate is made of a transparent plastic which has a rear [right-angled]
edge so can be parked so.. to reduce the desk-top footprint
