Laisimo Wyvern Review

Updated on: 2017-07-27


This is one of those mods that I have been using consistently since acquiring it. Laisimo sent me a black and red one and I just love the red one. I already have well over 4000 puffs on it. When it’s sitting on the table next to all my other mods, I just seem to grab it a lot over all of the other ones. Like I said though, if you are a high wattage vaper and you enjoy your vape at above 150 watts, then this will not be the mod for you. However, if you are like me and you regularly vape under 125 watts and you’re looking for a good mod with a great screen and respectable TC, then the Wyvern would be worth a hard look. It feels and vapes great and it’s one of the smallest, most comfortable, dual-battery mods I own. If you vape under a 150 watts, this mod is DeucesJack approved.

How Does It Vape?

This is a great mod for under 150 watts. Vape this mod under 150 watts and you will get a great vape. Over that wattage and I’m sorry but it just does not feel that strong. I don’t believe that this mod actually does 235 watts. I have vaped it next to my FSK, Yihi, and DNA mods. I put my TFV12 Cloud Beast King on it at 235 watts. In all honesty, it didn’t feel like more than 160 watts. When I let the same tank cool down and put it on the other three mods that I mentioned, I got a significantly hotter vape. All three of those boards felt much stronger and much closer to the wattage than the X7 board. I even took all three of the other mods and vaped them at around 160 watts. I let the atomizer cool down and then I put it on my Wyvern at 160 watts. At 160 watts, the Wyvern did feel close but the heat did drop off mid vape significantly when compared to the other three boards. This is not really a big deal because I rarely vape over 160 watts. I just hate when companies are not honest about the true wattage of a mod. If you are going to advertise that this mod does 235 watts, you should be sure that it does and if it doesn’t, it should come a lot closer than the Wyvern does. While I may not vape that way everyday, I do know that there are some people out there that do vape consistently over 160 watts. For those types of vapers, this mod is definitely a no go. It is kind of a shame that Laisimo decided to exaggerate the wattage on this mod like a lot of other mod manufacturers out there do. Well, Laisimo, if you are reading this, do all your customers a favor and just be upfront about the wattage. Vapers will appreciate that a lot more than the feeling that they were lied to.

I would call this mod accurate up to 150 watts in power mode. When you are vaping it at under 150 watts, the ramp up is quick and almost instant. The response from hitting the fire button is very, very, quick. TC on the Wyvern is also extremely good. I used it in Ni and SS mode up to 100 watts and from what I can tell, it was certainly on point. One little pain I had when in TC mode is when you switch between wattage and temperature to adjust either one in TC mode. To make that adjustment on the mod, it requires you to hold the plus minus button for 2 seconds. Usually, you wind up changing the wattage or temperature by a tiny increment when doing this. It’s not a big deal but personally it wreaks havoc with my OCD.

First Impression Out of the Box

The Wyvern comes packaged very nicely. I really do like the paint on this one. It has an almost anodized looking finish to it. Pull it out of the box and boy does it feel light. It also feels great in the hand. It almost feels like I’m holding a block of aircraft aluminum. The screen is nice and big as well as centered. I can’t wait to see this screen lit up. I love the location of the firing button. So far, the build quality seems really solid. The initial impression is, I am impressed.

What’s in the Box

Not much to talk about here. All you really get in the box is the mod and a charger cable. There is also an instruction booklet and the warranty card. I do have to say that Laisimo did a nice job on the instruction booklet.

From Top to Bottom

I really like the 510 on this mod. The threading is stainless steel and it is really smooth. The 510 pin is springy and it does have a pretty long throw to it. The pin is also gold plated. The connection itself does not exactly sit flush against the mod, it does peak up over the body of the mod ever so slightly. So far, all of my atomizers have sat flush on it. It does have a weird sort of semi platform that creates a half of a circle look at the end of the mod. When you do run a 25mm tank, it will not overhang on the mod but if you look from underneath, you will see a slight overhang on the platform itself. This is really kind of wacky design. I have no idea why Laisimo would do this. They should have just squared off the 510 platform and it would have looked much better.

Moving on to the fire button, it is located on the top of the mod. There is a sort of angular cut out for it and it really is a very comfortable fire button. This will be one of the few mods that you will be just as comfortable finger firing it as you would thumb firing it. The button has a trapezoid shape to it and it is on the small side but the corners of it are rounded. It has a precise, clicky feel to it. It is very responsive and the mod does fire rather quickly. If you’re the type of vaper that goes around shaking your mod like a Maraca, then the fire button may rattle a little bit. However, during normal use, the fire button does not rattle.

The screen is what really sets this mod off. It has a 1.3 inch OLED color screen that is just absolutely beautiful. The screen will display your mode, wattage, temperature, resistance, voltage, battery life, and puffs. It is simple yet elegant and the colors are extremely vibrant and bright. You will have no problem seeing this display in all lighting conditions. I really do like the puff counter and the fact that it does not reset when you swap out your batteries. That is a really nice touch.

Laisimo Wyvern Review screen

My only problem with the color screen is I feel that Laisimo did not go far enough with it. What I mean by that is, it’s such a beautiful screen yet it is so limited. As far as I know, you cannot put your own custom wallpapers on there or any other wallpapers for that matter. The screen that is there is the one that you are stuck with. To me, that seems to be a big waste for such a beautiful screen. I think Laisimo would have been a lot better served had they taken the time to develop some software to go along with this gorgeous screen.

Below the screen, we have separate plus and minus buttons. They are both clicky and responsive as well as rectangular in shape. They look to be made of the same material as the fire button. Right below them, you will find the update charging port. While most ports are mounted horizontally this one is mounted vertically. In between the screen and the buttons there is some Laisimo branding but it is subtle and not intrusive at all.

Laisimo Wyvern Review battery

In order to open the battery door, you need to pull it down and out. To put it back on you, push it up and in. There is some venting at the top of the battery door and it does line up with venting on the interior of the mod. The door is rock solid and very well done. It does have a clip located at the bottom center and one strong magnet located at the top center. The battery door does not rattle, move, or come off during use.

The battery sled is another well done component on this mod. It has a clean look with a nice long battery ribbon. It does have dual leaf spring type of battery contacts that are probably made out of brass. On the bottom of the sled, there are button style contacts. Initially, the contacts can be a little tight in the beginning but after swapping out your batteries a few times, they do loosen up. Of course, the battery sled does have clear battery orientation markings like most mods do today.

The Look, Feel, and General Aesthetics of the Mod

This mod has a beautiful finish to it. It has that anodized look that just pops. I like the way they did the paint on the Laisimo Wyvern and so far it has been pretty durable. Combine the paint with the beautiful screen and you have a very elegant looking mod with extremely clean lines. The nice thing about the Wyvern is, no matter which way you prefer to hold it, it just feels great. It is also very small for a dual 18650 mod. I put it next to some of my smallest 18650 mods like the Ipv Vesta, Joyetech Cuboid Tap, and the Smoant Battlestar. Next to every one of these mods, the Laissimo Wyvern is smaller. In fact, when I put it next to my Vaporesso Tarot Mini, which by the way is a single 18650 mod, it is only slightly wider and deeper. Believe it or not, it is actually shorter than the Vaporesso Tarot Mini.

The Board

The board used in the Laisimo Wyvern is their proprietary X7 chipset. Like most full function mods today, it does have the full temperature control suite and a TCR function. The chipset also has a bunch of protections built in like high temperature, check atomizer, work overtime, and atomizer short. If you do see the work overtime message it means that the mod fired for longer than 10 seconds in wattage mode or longer than 20 seconds in TC or TCR mode. The X7 chipset has a resistance range of .5 to 2.5 ohms and Laisimo says it maxes out at 235 watts, but I’ll get to that later.


The Menu System

The menu system on the X7 chipset is just as simple as can be. The really nice thing about this mod is every time you screw on an atomizer, it does ask you if it’s a new coil or not. That is just fantastic and I love chipsets that do this consistently. Next, you simply select yes or no and confirm by hitting the fire button. After that is done, you have to pick your material. You can scroll through all of them by using the plus minus button. Once you find the right material, you hit the fire button to confirm and you are ready to vape. I know, when you write it out, it sounds like a lot but in real time, it literally takes 2 to 3 seconds.

  • +/- together for 2 seconds lets you choose your material
  • In TC/TCR Mode, +/- together lets you switch between wattage and temperature
  • Hold the + button with the fire button to lock the device

The screen will go dark with no use in 10 seconds. After 18 seconds, it will go into sleep mode. In order to wake the mod up, just hit the fire button. Another nice feature is when scrolling the mod, it does scroll very fast.
