I have 4 CE3's (the worst purchase I have ever made) - Trash, right out of the packet.
Loads of bad DIY Juice - I had a lot more, but a friend of mine seems to love quite a few of what I consider to be unvapeable flavours so she takes quite a bit of my old juice off my hands
Juice I did like at first, now hate. I'm keeping it to see if I like it again once it has steeped for a year

Old crappy kit Atties. One I debridged, used once. Got bored with dripping within an hour.
Loads of Cartos which I have filled with the above bad juice. I might like it in the future

E-Lites mall style kit bits and bobs. Not a full kit. I should trash it really.
100's of part-used carto condoms - I know, right?
Loads of premixed nic juice (unflavoured) - Around a litre - I kinda got bored with DIY. I only managed to make 1 semi-vapeable recipe. I now keep it to mix up the horrid recipes my friend loves. I'm keeping this in case the world ends or they decide to make it all illegal in the UK. Most of it is in the freezer.
Old no-name 18650 charger. Don't trust it.
Couple of really tight DC tanks which are more trouble than they are worth.
I have been fairly lucky, I tend to do my research and know what sort of stuff I like these days. I'm slowly getting rid of it to poor unsuspecting friends who have just taken up vaping.
