This third tank is accidentally a big test of the product. It's been a while since I've vaped anything with this type of plastic and I put some 80/20 lemonade in there. So far it hasn't cracked but the plastic is fairly cloudy. When shaken, this juice turns cloudy and opaque, so that might be why. I'll update you all if something changes.
Well, here's the update! Something
seriously changed. Long story short, don't put lemonade in your new ce5. Just don't.
I guess I got my wish, this thing won't be making any more noise.
Oh well, it's all in the name of testing! As you can see, strong citrus flavors aren't likely to go well in this. The lemonade was sweet and sour and a very accurate flavor. I didn't even think before I put it in there since I've been using it in the Phoenixes for a while.
As I stated in the above quoted post, the tank got cloudy pretty quickly. I vaped through it and it tasted fine. It looked fine. I didn't notice any of the black ick in the tank. Once I finished it up, or as close as possible since you just can't get that last bit of juice, I tried to twist the top off. It gave me some extra resistance but I got it out and it was a big melted mess!
You can see in the pictures that some of the tip was left in the tank. It was like the tank scraped the sides of the tip off as I was pulling it out. Maybe it's the plastic that tip is made out of because there's a thread around here somewhere about stardust tips melting with cinnamon/big red flavors.
That nasty brown/black stuff on the side is from the melted tip. I guess there was some juice up near the top that washed down some of the melted plastic when I took the tip out. I dunno.
Anyway, I can't test it any further obviously, unless I figure out how to take it apart, clean it out and put it back together with one of my old stardust tips. It's worth a shot.
Final review-
Performance - 5/5
Vapor - 5/5
Flavor - 5/5
Durability - 2/5 - Too easily damaged by acidic juices.
Disclaimer before someone jumps on me about it: 3 tanks isn't enough to properly test an item. Regardless, this is information worth knowing. This is just what I've experienced with the ce5. I wish I had another one
I'd just stick to strawberry cheesecake
so I just let it pass ...my bad sorry
