I've actually used a nice work around to get the super soft silicone bottles to work and seal perfectly. Both of my DS's and TS (all genuine from 528 or defiant designs direct, are in perfect working shape all with silicone bottles, which is why I love them. The parallel setup allows batts to last so much longer while putting less stress on each individual cell. The fact that it is putting less strain means less voltage drop on each cell, really allows for hard consistent hits. The silicone bottles I'm using are the yftk 8ml ones and with the work around they are much more enjoyable than those pc hard ones that comes stock, cant stand those hard bottles. I was just saying I'd like to buy a 3rd DS for backup because they're discontinued, I think. Not sure why they would discontinue such a great product. Sourcing parts directly from defiant designs is somewhat hit or miss but I have heard of people ordering replacement buttons and springs etc..for me they are the ultimate setup for squonking and come with a good amount of accessoriesfor repairs. I have about 4 or 5 of the stock bottles that I will never use, if anyone has a need for them.. but I'm holding onto the metal tube assemblies because I use those with the silicone bottle workaround. My buddy bought a clone from 3f and I had to fix it for him because the 510 wasn't protruding from the casing or spring loaded, which is odd. I had to mill out the delrin 510 holder so the 510 sat higher, allowing it to make contact with the atty, bad milling or spec design I assume. I got it working and it really doesn't hit as hard or consistent as the genuine. So if anyone has a new in package DS they would like to sell, please let me know. Sorry for the rant, I was thinking of getting a different dual mech squonk but I love these so much, it's hard to stray
