This mod was an afterthought after my shopping , I thought well its only £23 . I have many squonkers of varying prices right up to the high end ( Lost vape and Dotmod ect ) including mechs , Its ok for the money , it works well , I use it if I'm working on the garden for example , its a good training tool if you want to get into mechs or squonking or both for not much money , build quality isn't the best but good enough , its seems safe for a mech , the squonk bottle is a bit squashy but it has to be because the fill system is via a bottle through the 510 pin provided with the mod . It works better with a 21700 in it . Stick a wasp nano on top and your away on a budget, recommended . Excellent service from 101 as usual .
