Solid, but it can be hard to take apart
I've had this tank for a while now, and it's rather high-maintenance. After a few months of use it's started to get very difficult to take apart. There's three moveable parts to the black metal body, and I've had to break out a wrench a few times to twist the middle part off to change the coil, I've cleaned and greased the threads, but it doesn't seem to make a difference. You also HAVE to use pliers to take out and put in a new coil. The top part where you untwist and then slide to fill up gets stuck sometimes as well. For all that though, it works great and the low ohm cotton coils for this last for WEEKS despite being very small. My juice stretches longer, and I get the full flavour without a huge cloud.
Excellent and easy to use

So happy with this, has a similar feel to a cigarette, if that's what you're looking for
The flavour is immense as are the clouds highly recommended!!!
