I’m back once again today to present yet another review. This time I will be attempting to cover the EH Pro Cold Steel 100 mod. This mod seems very small in the hand for a 21700/ 20700/ 18650 mod and is very comfortable to hold. Although it’s not one of the most popular brands out there, I think it’s a very nice and simple mod that can fit in a pocket and still last me through the whole day for my style of vaping. Let’s see what’s included and I’ll give my opinions on it so you can judge for yourself if it would be a good fit for you also.

FIRST IMPRESSIONS:
The Cold Steel 100 comes in quite a different package than what I’m used to seeing. The box itself is quite small and when opened I found what appeared to be a belt holster like one would store a pocket knife in on their belt. However, it doesn’t appear that there is room once the pouch is closed that there would be room for a tank on the mod if you were actually going to wear it on your belt. Besides user manual and warranty card, there is a USB mini charging cable and 18650 battery adapter included.
The mod itself reminds me of the old Zen mods from years ago or even somewhat similar to the SX mini. Its basic design is a battery tube with the board and closure mounted on the side. I know the picture above shows the Ambitionz Vaper logo above the fire button but the one that I received does not have that. As a matter of fact, the mod doesn’t have any kind of markings or branding on it besides the Cold Steel stamped into the metal on the back of the unit on the bottom. With the black version, it is barely noticeable.
The one I received is black. It seems like a decent finish on it. From top to bottom on the face of the mod is the fire button, display screen, + and – buttons, and USB mini charging port. When the mod is first turned on the display shows Cold Steel. The display is a little small compared to some more current mods. The display shows the mode (normal, soft, hard), atomizer resistance, a battery level indicator, voltage of current puff, and in larger font the set wattage. The operation is as follows:
- Press the fire button five times to turn on and off
- Press the fire button to go to the mode menu and use the + and – buttons to scroll through the available modes( Power, Temperature control, Curve, Bypass, and Volt)
- Press the + and – buttons to lock the mod from firing or adjusting
- Press the fire and – button to flip the screen
- Press the fire and + button to lock the adjustment buttons
- Press the fire, + and – buttons to go to stealth mode
FINAL THOUGHTS:
Overall I liked the simplicity and the feeling in the hand of the Cold Steel mod. Yes the display is a little small and doesn’t show a ton of information on the screen but sometimes simple is better. The mod is very small and lightweight in my opinion for a 21700 mod. Sometimes it’s hard to put into words how well a mod feels in the hand. For me, this is one of the most comfortable to hold 21700 mods that I’ve tried.
It has all of the basic modes that you see on most mods. I usually don’t use temperature control and am for the most part a wattage vaper. I used to play around with some of the curve functions on different mods but to me it wasn’t usually worth the trouble. I like that the mod will fit a 25mm tank comfortably. I have heard some remarks about this mod being a copy of the SX mini but you could get a few of these for the same price as one of the SX. I do own an SX and yes it is similar in design. The cold steel is smaller and lighter weight. No it’s not a high end mod but seems to function well in my opinion for what it is. If you’re looking for an inexpensive 21700 mod that works well and doesn’t have a noticeable lag on firing then it may be a good fit for you. So would I recommend the EH Pro Cold Steel mod? Yes I would. It may just be my opinion but I very much like it and plan on continuing to use it. As usual, a big thanks to Sourcemore and Lilia for sending this for review.
