What are everyones thoughts on the Sx Mini? I have seen the reviews but more wondering about mod for money. I predominently use a kayfun with Ni and rarely will vape over 40 watt so I don't need a high wattage device. Dollar for dollar is this the best device for the money or are there better VV/VW box mods out there to look at. Keeping in mind I prefer a more compact mod. Thanks for your input.
