This is almost as good as the Voopoo RTA and way better than the previous Soulmate RDTA. Would recommend less experienced rebuilders to go for the Voopoo one, as this is harder to build. If you want a bigger coil then definitely go for the other. This also has a smaller mouthpiece, plus the ability to change to an MTL mouthpiece and different airflows which will benefit MTL users. Clearance above the coil is not very big and with exotic coils they can touch the top of the metal chimney inside. So you are really limited on coil size. 2nd image (if they are ordered correctly) with the larger 2.5mm Staircase coil only just fit in the gap, and when the top was tightened on caused it to short. The 3rd image with the 2.0mm Tiger coil works well, but if the cap is tightened fully then it also shorts.
All in all it gives a nice vape. The different coloured parts are cool but unfortunately isn't one which will match my Bronze Knight mod. I basically am using both in rotation now and just use different juices in each so I can switch flavours. I don't vape MTL but think this will probably be better for that than the other tank.
