@tara81 – your concerns toward a mesh RDA are valid. But would just like to address that every RDA has its own quirks and learning curve. Mesh, most notably the Profile RDA is no more difficult to setup than your usual single or even dual coil RDA – it’s just different. Once you become accustom to how it works and what is needed to set it up, which does not take long at all, it becomes second nature. If you are a fan of mesh subohm tanks, the Profile RDA offers a lot of similarities.
The low mass and high surface area of mesh is very efficient in comparison to a many coil-based setups. The positive to this is you enjoy instant ramp up time with little needed power. And because of its low mass, it cools back to room temperature instantly which can lead to a more consistent vape especially if you chain vape a lot.
The amount of cotton that is needed for mesh, which is roughly 3x that of a single 3mm coil, may look intimidating and wasteful. But the wick lasts so much longer than a typical coil (sans dry burns) that in the end you are actually using less cotton. With some of my sugary based juices, which dictates a re-wick after 3 to 4 days with a regular coil, my wick with the Profile has lasted over a month and even then, it did not look any worse for wear.
As for flavour – flavour is very subjective so you will always receive many different opinions on it. The Profile is very flavourful, but because it is a fixed system, meaning there is no coil positioning needed, it offers a very consistent flavour. Where with a coil you may have to tinker to find that sweet spot. In the end only you can answer whether the flavour it offers suits you or not. Unfortunately, that means you have to try it to discover for yourself.
It is true that mesh is less forgiving than a typical coil in terms of dry burns – they can come suddenly and be quite aggressive! But once you discover where that threshold is, which again is a short learning curve, dry burns become a thing of the past. The Profile helps mitigate this with a spring loaded pressure plate under the wick - so as your cotton degrades, the plate is pushing the wick up against the mesh alleviating any voids that can result to hot spots which is the cause of dry burns. And of course you just have to ensure the wick is nice and saturated…but that is a given for either system (coil and mesh!)
The biggest con that I see with the Profile, is that it takes a lot more effort to squonk. The cotton which resides directly over the squonk pin does create a bit of back pressure which grants a harder squeeze of the bottle. And because there is so much wick, you may have to squonk a few times in order to fully saturate. But this could be lessened by changing the frequency in which you squonk.
Despite being a huge fan of the Profile RDA I won’t say that it is better or worse than your usual coil based RDA – just different. That difference has great value to me and judging by some of the comments on this thread along with others, many feel the same.
Long post but hope it clarifies some of the misconceptions with the Profile mesh.
