Envii Loch Ness Review

Updated on: 2017-06-30


All in all, the Envii Loch Ness is an extremely capable mod with a ton of features that will appeal to a wide cross section of vapors. Like most mods, it does have its quirks. This one may have a little more than the others but the look, build quality, and form factor definitely outweigh them. It is definitely one of the most ergonomic mods I have ever held and that feature alone may attract a large following. It looks great and feels great which is always a big plus. That’s not to say it doesn’t vape well because it does. It gives the buyer lots of choices and lots of modes. All the choices and modes work either very well or are more than respectable.

At the end of the day, it’s a solid dual 18650 mod. It may be a little on the pricey side in its very crowded category but the build quality and ergonomics you get for the price of admission are more than worth it to me. With all the choices in the Dual 18650 category, you could do a lot worse. It does have a very premium feel and look to it without breaking the bank.

How Does It Vape?

This mod Vapes very well and gives the user a ton of options on how they like to vape. Between the boost, smooth, curve mode, TCR, TFR, and all of the temperature control settings, you have a lot of options with the Envii Loch Ness. Oh yeah, let’s not forget it also does power mode as well.

I like the way this mod Vapes in power mode. However, no matter what mode you are in, it seems to have a slight delay upon firing. It seems to be very accurate in power mode and other than the slight delay, I get a very satisfying, accurate vape. TC mode is also done very well but I would not put this chipset up there with the top tier TC boards like the DNA or Yihi chip. While it does a very respectable job in TC, it’s more in line with the second-tier boards like the Innokin Atheon and the VO chipset.

While all the advanced setting modes are very nice and I’m sure some users will enjoy them. It really isn’t the way I Vape on a daily basis. Most of the time I am in temperature control mode. The advanced settings are nice to have but they are nothing groundbreaking and most of it has been done before in some form or another.

First Impression Out of the Box

This box opens in a weird way. It kind of opens from the corner and slides out. Packaging is very nice. The mod itself has a rubber Vapor Shark-like coating. When you first hold it, it feels extremely comfortable. Envii is going to have to do a lot better than just fancy packaging though. So let’s dive down and take a serious look at the Loch Ness.

What’s in the Box

  • One Envii Loch Ness 150W Mod
  • Flat 510 Adapter
  • One Proprietary Micro USB Cable
  • User Manual

I want to give credit to Envii for producing a really nice user manual. It is laid out beautifully and goes over everything in plain simple easy-to-understand instructions. It even has some graphics included as well. Very nice job Envii.

Envii Loch Ness Review Box

From Top to Bottom

As usual, we’re going to start off with the 510 pin on the Loch Ness. It is very flush to the mod. It is a really high quality 510 pin with stainless steel threading that is buttery smooth. It has a gold plated pin that is springy and has a really nice throw to it. This may be one of the better 510 pins I’ve seen on a mod.

However, we cannot stop at just the 510 pin with this mod because there is more. This mod comes with what looks like a beauty ring. In fact a lot of other reviewers have said that it is a beauty ring. I’m here to tell you that this is not a beauty ring but that it actually replaces the actual 510 plate. Unfortunately, Envii did not include a tool with this mod to remove the 510 plate. I used a set of tweezers to get the installed 510 plate out. Once removed, you can replace it with this catch cup plate that basically gives you a recessed 510 connection with a cup to catch juice. The catch cup will accommodate 22mm atomizers. While I did install the catch cup and it did work rather nicely, I do tend to use larger atomizers and tanks on this mod. This little option is perfect for the vapor that drips all the time and is a sloppy dripper. This will alleviate that problem but you will be limited to 22mm RDA. All in all, it’s a nice touch but, for me, unnecessary.

Envii Loch Ness Review mod

Right below the 510 connection on the mod, you have a circular stainless steel firing button. It seems to be mounted a little too high for me. I would have rather them slide it down three or four millimeters in order to make this mod a more comfortable thumb fire mod. That is not to say this mod is not comfortable to thumb fire because it is. In fact, most people that like to thumb fire will really enjoy this mod. The only reason I think the fire button should have been located a little lower is because when I grabbed this mod my thumb automatically goes to the point just below the button. The button itself is very high quality and has a clicky feel to it. There is also a kind of hollow sound that the fire button makes that I just wish wasn’t there. It almost sounds kind of tinny.

Right below the fire button, you have two stainless steel plus and minus buttons. They are clicky and tactile in feel and lacked the hollow sound that the firing button has. They are nicely done but they are kind of small for a mod of this size. I do wish they were just a tad bigger.

Envii Loch Ness Review screen

Below the plus and minus buttons, we have the screen of the mod. It is bright and vibrant and I can see it in most lighting conditions. It has all the information a vaper would want to know including the wattage, temperature, mode, resistance, volts, and a dual battery meter. My one little complaint about the battery meter is that when the batteries are full, there is no spacing between the two battery meters and it looks like you have one gigantic battery meter until you fire the mod and the battery meter goes down a little bit. Once that happens, you will see the spacing between the two separate battery meters.

The battery door is done very well. It is smooth and secure. I think the battery orientation markings could have been done a lot more clearly. While you can see them, they do get kind of blurry after putting batteries in and out a few times. This is because they are engraved into the battery contact of the battery door. So far, all the batteries I have used fit nice and tight and there is no battery or battery door rattle. Simply push down and slide in to secure the battery door and slide out and pull up to unlock the battery door. On the outside of the battery door, there is some black on black branding that you actually have to really look closely to see. It is subtle and elegant and I don’t mind it at all. The body of the mod actually looks like a typical C-frame type battery door but it is not. It is all one piece and kind of deceptive looking in that way.

Envii Loch Ness Review Battery

If you are facing the mod right below the screen, on the right side of the mod there is a USB charge update port. This will be one of the biggest cons for the Loch Ness. I don’t know why but for some reason Envii decided to recess this port. It is so recessed that you actually cannot use any other wire except the one that is included in the box. You need an extremely long plug in order to access the recessed port. I don’t know the reason for this but it definitely hinders you being able to charge the mod on the go and just grab any wire to do that. If you want to charge the Loch Ness on the go, you will need to make sure you have your Envii charge cable with you because no other cable will work. Kind of ridiculous in this day and age that a company decided to go with a proprietary update charge port. The other major con to a charge port like this is if you do lose the Envii cable, your ability to update will be lost as well. Going forward, I hope Envii takes a serious look at this and corrects this serious issue.

The Look, Feel, and General Aesthetics of the Mod

The look feel and aesthetics of this mod is on point. This mod has beautiful contours to it that feel phenomenal in the hand. It has a Vapor Shark like rubber coating to it that seems to be pretty durable. The texture is extremely smooth and feels very nice to the touch. The size of the mod is kind of on the tall side for a dual 18650 mod. I think if Envii would have kept the same form factor yet gone with a shorter style, the mod would have been a lot better. All that being said, this may be one of the most ergonomic mods I own. It is definitely one of the most comfortable to hold as well.

The Board

Envii uses a proprietary chipset for the Loch Ness. It has a full temperature control suite. It also has advanced preheat mode, smooth mode, curve mode, TCR, and TFR adjustments. Wire capabilities in TC mode include nickel, titanium, stainless steel 306, stainless steel 316, stainless steel 317, and tungsten. The loch Ness will fire as low as .05 ohms and as high as 3 ohms. Its wattage range is from 5 to 50 watts and its voltage range is from 1 to 8.5 volts.

Safety features that are built into the board include high discharge warning, reverse polarity protection, output short circuit, overheat, and an atomizer time limit. The High Discharge warning will display when the batteries are not suitable for a high drain. Reverse Polarity will protect you against putting the batteries in backwards. Output Short Circuit will let you know when you’re atomizer has a short and will show the message shorted. Overheat protection will display when your atomizer is too hot. On the screen, you will see a TOO HOT message and it will not let you fire the atomizer until it has cooled down. The atomizer safety feature ensures that the mod will not fire for more than 10 seconds.

The Menu System

  • 5 clicks on/off
  • Hold all three buttons to enter advanced setting mode
  • + and fire button lock wattage and temperature adjustment
  • -/+ together set resistance
  • In TC mode – and fire button allow for wattage change

Once you are in the advanced settings menu, you will have a choice between boost, smooth, and curve.

Boost mode is a power boost function that uses an algorithm in the chip to adjust the maximum boosting wattage. You can set the amount of boost you want and the duration of time you would like that boost to occur.

Smooth mode is a setting that is used for atomizers that might run hot or overly harsh. You can set how many seconds into your Vape you would like the power to be cut.

Curve mode is like a lot of other curved modes on a lot of other mods. It is designed so you can create your own custom curve in wattage mode. This allows you to let the coil wattage fluctuate up and down for however many of seconds you desire. Lots of people love curve mode and the mode on this mod is very good. It reminds me a lot of the curve mode on the Amodus boards.

In the system submenu is where you will access the screen and USB link. Under the screen setting, you can change the orientation from left to right or have stealth mode on or off.
