Am new to mechanicals having got every regulated squonk that can do 100w (which there are very few..wtf). Topside now rules and all my others are redundant back in their boxes. No one can match 12ml and a spare 12ml bottle and I can just swap rdas to suit my wattage over 100w or less. Definitely the best squonk STILL after all these years. Beautiful, strong reliable. The only improvement would be the release of a Series squonk witthe the same or smaller footprnt. Thank you Sigtips for not being out of stock 👍👍👍
