The only downside to glass tanks is their tendency to crack or break when you accidentally drop your vape. There's no need to buy a whole new Cascade SE Sub-Ohm Tank, as Vaporesso manufacture replacement glass tubes.
Genuine Vaporesso Cascade Baby SE Replacement Glass kit is made from clear toughened Pyrex glass and comes with two spare O-rings to ensure leakage is kept to a minimum.
One thing to point out is that the Cascade Baby SE 6.5ml replacement glass is not compatible with the previous version Cascade Baby 5ml and Cascade Mini Sub-ohm 3.5 tanks.
