Sigelie100, Cloupor T8 & T6, all are fine box mods. Their best performance and vape potential lies with builds between 0.5-0.8 ohms. Find I prefer the T6 & T8 the most, though the Sigelei is a strong box too. T8 has big balls, but the T6 feels best in hand. All three provide an excellent vape.
Must say though, simply love changing the batts out on the Cloupor's, what I love about it is the Matrix screen sign in. For some reason that cracks me up every time I swap the batts or power up.
