Therefillable and replaceable pods perform extremely well in our tests with our N.E.T EL TORO liquids producing thick vapour and maintaining good flavour even after a full week of vaping and about 50ml of liquid. Overall, the performance of the pods remained good, while the quality of the flavour exceeded our expectations! The PURO PODS are 100% leak proofand in the over a month tests we perform we didn't even noticed any leaking, or moisture.
