Worked for me straight out of the box with no tinkering required.
All three battery sizes fitted.(18650/20700/21700)
The two 10ml squonk and the 30ml refill bottles are a perfect softness with very high quality two part stainless steel cap.
Sliding removable side/front panel gives easy access to change battery and remove bottle and inside, the silver plated copper battery/switch contact strips are well made and solidly attached with a screw to the case and nut to the 510.
No arcing at the switch, no leaks from the bottles or 510 connection when in use and insides have remained completely dry after 100ml of juice used over the past week.
All my RSA’s have sat flush to the box due to the large travel of the spring loaded 510 pin available and the shape of the mod ensures it’s comfortable in the hand with either finger or thumb firing.
The 30ml refill bottle is great for on the go top ups of the squonk bottle by screwing onto the 510 connection, enabling you to get the maximum amount of juice in without any mess.
Switch has just the right amount of resistance/springiness and makes a solid connection with just the right amount of travel which can also be locked by sliding the button up and it stays in place until unlocked.
The box is very light and pocket friendly but also extremely tough and a quick wipe over cleans up my daily work grime to good as new.
Outstanding high quality, low cost squonking kit.
