The Merlin Nano MTL RTA was sent to me for review directly from Augvape. Hot on the heels of the popularity of nicotine salts, low-wattage, and tight draw vaping, the Merlin Nano MTL is a rebuildable mouth-to-lung vape. I’m a huge fan of rebuildable MTL atomizers, so I’ve been really excited to share this one.
The Profile Unity RTA was sent to me for review from Wotofo. Get it here for $39.99 (affiliate). This is the RTA version of the super popular Wotofo Profile RDA, which a lot of people believed was one of the best RDAs or even one of the best vape products of 2018. And I thought so too. The Profile RDA is awesome (here’s my review of it). So does the Unity RTA stack up? Let’s take a look.
The Expromizer V4 was sent to me for review from HeavenGifts.com. You can get it here (affiliate). This is a tight-draw tank from EXvape and it’s designed in Germany and made in China.
I’ve never used any of the previous versions of the Expromizer, but I did watch Todd’s Reviews take on the V3 just to get an idea of what might have changed. The V3 had bottom airflow, a lot of parts, a juice flow control, and 4ml extension parts. Nothing bad, but definitely more complicated than your average tank. The V3 was able to do restricted lung hits, so it had quite a bit of airflow. Todd was also vaping it around 26 watts. The max coil size was about 2.5mm inner diameter, and maybe 3mm with a basic round wire build. The juice flow control wasn’t visible from the windows, which was poorly thought out, but other than that it was machined very well. He said the flavor was very good too. One of Todd’s complaints on the V3 was that the airflow hole beneath the coil was too big at 2.6mm diameter. He said it still worked well, but he felt that the draw would be better with a smaller airflow hole under the coil.
Ok, so we know a little about the previous version so let’s see what’s new.
