NANOS | Nanos Single tube | mmvapors.com
Check out the new Nanos mod from MMVapors(builders of the Poldiacs). It has a bottom switch.
In 18650 mode they are 83mm tall. The bottom switch both works and locks with magnets. You only have to rotate the switch 7mm to lock or unlock. This action can be done with your little finger. This switch is only 7mm tall, with less than 3mm of this outside of the battery tube.
This mod will be released probably by the end of this week and is available on preorder at the present time.
This short length is with a full top cap, not a recessed top cap. We are trying to get them to offer a recessed top cap as an option in the future. This would make the mod in 18650 mode only 78mm tall as the full top cap adds 5mm.
Owners of Poldiacs can convert them to this new bottom button design by purchasing the switch and a Poldiac to Nanos adaptor ring.
I have a 18650 Nanos in polished brass on order and I am really looking forward to receiving it in the very near future. I ordered it on April 1st when they first offered them for sale.
