I have 21 Mesh RDA's (9 Dovpo Mesh Pro's, 9 Wotofo Profiles and 3 Vandy Vape Mesh RDA's). Mesh RDA's are almost all I vape now days.
Everything
@Punk In Drublic said is spot on.
My personal favorite is the DMP's, but the Profiles are a close second. The VVM's have next to no drip well so are the most problematic in use. The Profile is the one I would suggest anyone new to mesh start with. It is the easiest one to build 'correctly' with the very first build. They only come with KA1 strips (.18Ω), OFRF nexMesh strips available for them are also KA1 (0.12Ω). So for SS I use a roll of Vandy Vape SS mesh or SS sheet mesh cut to size for them.
***A note about the bottom fed atty's referred to from HalfAssedTech above... Like with their promised ship and/or delivery times, their product descriptions are often misleading or are in fact a bald faced lie. Just two of the reasons why I have done business with them only a few times over the past 6 years. The 'last time' (below) was the last time - I closed my FT account.
I'd be leary of either of those from FT listed above... they call them 'Dripping Atomizers'. One is a clone of a DMP, the other appears to be a clone of the VVM.
Case in point... I opened a ticket and contacted them about the
$10.48 Mesh Pro Styled RDA listed above and specifically asked them if they came with a BF pin. They assured me that they did, twice. Well, they do not come with a BF pin... IT IS A DRIPPER ONLY. They also do not come with any spare parts like the authentic one does (other than a worthless small DT, nothing else at all). How do I know? I bought 3 of them when the supply of authentic Dovpo Mesh Pro RDA's dried up some months back. The $31 and change was not enough cost for me to bother with their return policy that could take forever as slow as they are with everything else.
So I'd be suspicious of any BF atty they list for sale actually being a BF atty.
