I've only had that happen once and I was pressing it really really hard
and I'm not saying it doesn't happen, I completely agree with everything he said
it's not the best design but it works a heck of a lot better than the lift siphon system
I've been using it for 2 years and as said only had that happen once and I was really really stressed at work and took it out on my squonk

other than that after 2 years of use the silicon broke/tore a hole where my nail presses into it
I wish someone would redesign it though
you can turn any mod into a squonker so I mean buy you a cheap 2 battery mod and this is still cheaper than most dual battery squonkers...or if you have a 3 battery mod

which was my plan for this but fell in love with my aegis legend instead

hard to say no to a 7ml dual battery shock proof, water resistant squonk mod
