My method for testing the rest of the Protanks (video)
Before hand notes.
I dont put the Protanks into a boiling pan of water as part of my testing, I was only demonstrating the very high quality of the Kanger Protank in hot water as regular glass would simply crack.
Each Protank that ships will be tested before shipment hence the $28 dollar price tag.
The next batch will be fixed by KangerTech and this will not be necessary on future shipments.
