red and black box mod

High powered regulated box mods are becoming more and more popular with vapers. However, mechanical mods have a niche, almost cult-like following.

The Nemesis mod by Atmomixani is wildly popular due to its sleek design and versatility, which also make it one of the most cloned devices. Today we will be looking at the HCigar Nemesis clone.

The Nemesis is a sleek-looking mechanical mod. No matter what your color preference, you can probably find at least one version to your liking: brass, copper, stainless, even colors. I went with black because I already have several mods that need to be kept polished, and I didn’t want another one.

The black Nemesis combined with a high polish RDA on top looks amazing.

The firing button on the Nemesis draws the ire of many vapers, and is often described as “crunchy”. By far, it is the worst firing button of any mech mod I’ve used. I hoped to sidestep this issue and installed a magnetic upgrade by following Todd’s tutorial video:

This a mandatory upgrade that vastly improves the firing button in my opinion.


The main draw to the Nemesis is its versatility, because every aspect of this mod is adjustable. If you’re looking for a stealth vape, the Nemesis in 18350 mode with a small atomizer, like a Tugboat, is about as tall as an 18650 battery. That’s tiny.

The mod’s top cap has two adjustable airflow holes that can be wide open (both holes open), one hole open, or both holes closed. Personally, I closed off the Nemesis airflow when using an RDA because the draw was too airy.

There are several pieces to this mod, and it takes a little bit of experimentation to get the kinks worked out of the Nemesis at first.

Tip: Start by attaching your atomizer first, and work your way down the mod towards the switch.

One caveat is that you can’t really use the beauty ring with an 18650 battery. If you do, the switch has to be turned out really far, which only makes the crunchiness worse.


While I wouldn’t call the Nemesis a “hard hitter”, it’s a solid performer.

This is a very compact mod, so no matter what configuration you’re running, odds are the Nemesis is going to be smaller compared to your other mech mods with a similar setup.

If you’re someone who is just looking to get into mech mods, I would highly recommend the Nemesis. Its versatility allows a new vaper to experiment with various setups and discover what they like. Experienced vapers and collectors could probably skip this one. The Nemesis does a lot of things, but doesn’t do any one of them particularly well.

The quirky firing button is the main drawback of this mod.
