Excellent taste with the triple coil, easy to clean. HIGH LIQUID CONSUMPTION but nowadays I don't know many atomizers that don't have it, even RDTA. I never had a problem with leakage. Absolutely none. I have tried all 3 coils:
Double, good but nothing special.
Triple simply excellent, amazing flavor, relatively normal vaping watts.
Quadruple... good, not as much as the triple and with much higher consumption both in liquid and battery.
As for the coils that are said to be bad or don't last long, I haven't seen anything like that. With my own homemade liquids and 70%-30%, the coils last as long as it takes to finish a 120ml bottle. Now if you finish that in 3 days, it's not the coil's fault. You've done 3000 puffs. It's logical to need a change. Even with rebuildables, you change cotton every 3 days. If you vape commercial liquids with sweeteners, yes, you'll change more often.

As an owner of the Zeus subohm tank, I have both positive and negative feedback.

The design by GeekVape is very good, it is not as big and bulky as I expected based on the reviews. It fits very well on the Thelema Quest without any overhang, overall a very nice and user-friendly tank.

Flavor-wise, I expected more. There is a noticeable difference in flavor and vapor production compared to the previous Zeus Subohm tank, but it is not a significant "upgrade." Given the size of the coils and the amount of cotton, one would expect a bigger difference in flavor.

The airflow is slightly more restricted than the regular "Zeus," which personally doesn't bother me. With the single coil, it is more airy.

If you are expecting flavor similar to an RTA/RDA, I would advise against purchasing it.

I have paired it with the Geek Vape S100. Very good build quality, zero leaks in any orientation, does not spit liquid or burn lips.
A small disadvantage is the slightly expensive coils it accepts. (M series)

The best Zeus in the series, especially with the triple coil!!
