I simply stopped using it when I got my (Arizer) Solo, plus I could get a good price for the combo and had the 250ml as well. I still think it is a great vape but the Solo can do pretty much everything the SSV does without a whip or power-cord, which makes it so much more convenient and fun to use in my experience. It's also very conservative/efficient and saved me quit a lot of cash on weed already.
I have however switched to another vape again, lol
I've started using a cheap Vapo Bowl with my Ehle a few weeks ago and I really enjoy this way of vaping. It has been my daily driver since and I want to explore these lighter based vapes some more. It's not as efficient as the Solo but still not bad at all, and well, just fun(to me). I think I just like playing with big torches, lol
I think two or three different kind of glass pieces would be nice to have, but I hope to stop there. I have to many expensive hobbies as it is already
