So I bought the new white LR Sidesho SS atty for dripping at home and checking flavors. Surprisingly it has a flat contact like the newer 902s. Anyway, I'm not sure if anything else is different about it but MY GOD does this thing produce AMAZING vapor and perfect flavor. Its been a while since I bought a Sidesho atty, but regardless of how small these things are, this is still the best atomizer in every category. Even I was surprised.
