The HCigar Sentinel M16 Clone is a mechnical telescopic mod made of brass/copper and aluminum material. It is a full mechanical mod which is strongly recommended for advanced users as there is no PCB (circuitory) to regulate your device. With it’s telescopic capability, you can use different sized rechargeable batteries and attach your 510 threaded atomizer or other related fitments for a nice consitent vapor hit. 2 holes in the brass body create ventilation along with silver plated contacts for greater performance. Each M16 clone has it’s own individual production number with logos.
Note: please DO NOT stack batteries as this is a mechanical mod with no circuitry, you will effectively double your voltage which can and will destroy attached devices.
