Today I’ll be reviewing the Reuleaux RX200S box mod from Wismec. This is the welcome addition to the Reuleaux family, being the big brother to the popular RX200. Wismec have stepped up the game in this model with a larger 0.96inch OLED screen. Another new addition is the ability to use TCR mode, which enables you to enter custom temperature coefficients for your heating wire of choice. These are two exciting new features that were lacking from the previous model.

Out of The Box
The RX200S looks unique to the majority of square type box mods on the market. It’s an odd hexagonal type shape, making it stand out from the crowd. The front of the mod is flat, housing the screen, buttons and USB port. From the face, the sides then flare out and house ventilation holes, and the back of the mod is round, which is the battery door. The battery door is held in via magnets and it has a groove on each side to grip the door when taking it off. Swapping the batteries out on this bad boy is a breeze.
The battery bay houses 3 18650 cells, and a ribbon that is laid behind the furthermost 2 cells for ease of extraction. The polarity for each cell is marked in the battery bay, so pay clear attention to which way they should be installed.
The 510 looks solid and is surrounded by a countersunk 22mm juice well that also sinks your tank or RDA into slightly. 22mm tanks or RDA’s look at home on top of this mod as they sit down in that well very snug. Larger atomizers fit fine as well, as there is plenty of real estate on top of the mod due to it’s size, there is no overhang.
Every tank or RDA I have attached to the RX200S makes a good connection due to the spring loaded 510 positive pin. There is no wobble in the 510 connection and everything sits nice and straight once screwed in. Don’t expect to see any leaning attys on this mod.
The RX200S has 6 ventilation holes, two on each side and four on the bottom of the mod. I have never had the mod overheat or malfunction due to being too hot. It certainly appears to keep it’s cool with that amount of ventilation.
The buttons feel nice to use and do not rattle or have an annoying clicking sound. They are placed ergonomically so you’re not stretching your thumb awkwardly to dial in your preferences and fire the mod.
The 0.96 inch screen on the front is certainly the biggest I have seen on a mod and displays information very clearly. The text is in blue and is bright enough to see in the dark or dimly lit scenarios. The most important information, current watts and temperature, is displayed predominantly in the middle of the screen. The other information is displayed smaller on both the top and bottom of the screen.
The aluminum alloy build material, feels quality without being overly heavy. Don’t get me wrong it’s a heavy mod once the 3 battles are inside, but it feels sturdy not cheap and flimsy.
Usage
For me, the mod fits in my hand perfectly with the curved section matching the curve between my thumb and index finger, using the index finger to fire. It does also feel nice to use it the other way round, using your thumb to fire and select with the natural grip of your fingers resting around the curved back of the mod.
Power on and off is the standard 5 clicks of the fire button or when you install the batteries it will be automatically powered on.
Menu navigation is very similar to the Joyetech mods, 3 clicks and the first parameter will start flashing, indicating that it is ready for your input. To cycle through the parameters you use the right button. To go to the next parameter you use the left button until it is flashing. When adjusting temperature, the menu will round robin between Celsius and Fahrenheit when you reach the top of the range. This is the same with watts, it will cycle back to the start rather than have to go backwards.
To turn on stealth mode, press and hold the fire button and left button together for 5 seconds. The screen will display “Stealth On” and then go black. The device will fire, but the screen will not light up. The adjustment button will still illuminate the screen. Do the same again to turn off stealth mode.

To flip the screen, with the device OFF, press and hold the left and right buttons together for 5 seconds. The screen will then show the new orientation of the menu display.
To lock the adjustment buttons, press and hold the left and right buttons together for 5 seconds. The screen will display “Lock” and not change any settings if either button is pressed. Do the same to unlock the adjustment buttons.
To edit your custom TCR values, with the power OFF, press and hold the fire and right button until the menu appears. Once you have input your desired settings, wait until the screen goes off before turning the device back on.
To monitor the state of each battery cell, with the device OFF, press and hold all 3 buttons together until the display lights up. The voltage for each battery will be shown enabling you to see if any cells are operating differently from the others.
Performance
When testing the RX200S, I was using a brand new set of paired HG2 3000Mah 18650’s. Wismec recommends using a paired set of batteries, meaning that they should be the same brand, same model and same age. The batteries should have a minimum discharge current of 25 Amps. They also recommend taking the batteries out the device to charge them.
Although the mod supports USB charging, I could only imagine it would take forever to charge 3 cells from the device. This is something I am yet to try, as I am hesitant to leave the batteries charging unattended. It is also recommended to periodically cycle the batteries through positions inside the mod to ensure even discharge over the life cycle. There is usually one cell that discharges a little more than the others within the RX200S – I’d guess it’s the one at the front of the battery bay that is opposite in polarity to the 2 at the back.
When using this device with an RDA, I get 2 solid days of vaping without having to recharge. This is typically between 60W – 80W at around 300 degrees Celsius. I’m mainly using stainless Claptons around the 0.1 ohm mark in SS temperature control mode. The performance in wattage mode is pretty much on par with temp mode, possibly slightly shorter battery life but very marginal.
When using tanks, it’s between 3 and 4 days before I need a recharge. Predominantly in Ni200 temp control mode with a coil around 0.17 ohms and this is vaping between 30W – 50W.
The battery meter starts to flash at around 10% capacity to remind you of low current and that you will have to recharge soon. I don’t wait until the mod runs out of battery life completely, I use this as a warning to charge my batteries.
The resistance reading in ohms is spot on compared to my other devices and resistance checker, so you won’t have to worry about faulty misreadings with this device.
In regards to the pocket test, the RX200S is a definite no. It’s too big, bulky and heavy to comfortably and reliably fit in your pocket. Unless you can put it in the pocket of a jacket, it’s more of a set down on the table mod next to your bottle of e-liquid and a beverage.
An upside to the weight and shape of this device is that it is very hard to knock over. Unlike smaller, lighter mods the RX200S sits rock solid and the pure weight of 3 18650 cells keeps it from tipping if accidentally knocked. I have even had it sitting in the drink holder in the console of my car and it never tipped or moved when cornering or on a bumpy road.
The firmware update process is very easy. Software is available on the Wismec website for MAC and PC. Simply download, connect your mod and run the software, it couldn’t be simpler.
The screen has a protective layer on it which can be peeled off if it gets damaged too much. So don’t worry about scratching the screen, it will withstand some abuse and day to day wear and tear.
Apart from the various colors available in this model you can customize your RX200S further by way of front and back covers, silicone sleeves, adhesive wraps and custom firmware – you’ll have to do some googling here.For menu customization, you can choose to display either puff count, puff time or amp draw. And you have the option of choosing a battery meter or a battery percentage.
Wrap Up
For those looking for a powerful device with huge battery life, the RX200S from Wismec is hard to beat. Backed by the RX200 chipset, this device is not expensive and is very easy to operate. It looks good and performs just as well.
It can’t be beaten on performance vs price by a long shot. If you’re interested go ahead and take the plunge, you won’t be sorry you did. It has not let me down in the slightest and I highly recommend it. Keep on vaping!
