Wismec RX75

The RX75 is the latest device from Wismec and is designed in collaboration with Jaybo. Apparently Vapingwithtwisted420 who is a YouTube vape gear reviewer also had some input regarding this product.

The RX75 features Variable Wattage and Temperature Control and supports all major wire types. In addition it is fully firmware upgradeable and comes with an included tank. The device requires a single 18650 battery which is not included.

Wismec RX75 styling and build quality

The first thing I really must point out is that the RX75 looks nothing like a Reuleux or an RX200 in fact it looks more like a Sigelei 150W TC and an IPV D3 had a child together and then disowned it and had it adopted by some other company.

The top of the device has a stepped design that is similar to the Sigelei 150W TC but in the case of the RX75 it has been reversed and the atomizer sits lower than the top of the mod. In terms of styling this doesn’t look bad at all and certainly helps to cut down on the length of the device when a tank is fitted. However it does present a minor problem and that is that you can only use 22mm diameter atomizers with this device because anything larger simply won’t fit.

The 510 pin is decent and spring-loaded so your atomizers will certainly fit flush on this device. The threading looks to be Stainless Steel so it should last you a good amount of time.

At the top of the device is the lock button so you don’t accidentally fire it when carrying it around with you. The button itself is fitted well but it is rather small and not easy to adjust. I found I had to dig my nail in underneath it and flip it between locked/unlocked and it did require a little effort.

The fire button is rather unusual and you squeeze it when vaping very much like the Smok XCube II. It certainly feels comfortable to use and is very responsive.

The battery compartment is really nice and the correct orientation is clearly marked. There is no ribbon to assist with battery removal but it isn’t necessary. The RX75 has a generous amount of venting with four large slots on the base and a further four slots in two pairs of two on each side panel.

The Micro USB port is located on the side of the device but it is fitted vertically which means you will not be able to stand the RX75 upright when charging. The RX75 is firmware upgradeable so you can download any updates directly from Wismec.

Now we come to the part that I really dislike about this device the somewhat daft screen cover. Unlike other devices where you can see the screen clearly Wismec decided that you don’t really need that and created a flip cover which hides it away along with the plus and minus buttons. I am assuming that they tried to be stylish and this is some attempt to streamline but it is completely unnecessary and it makes adjusting settings inconvenient.

Such was my loathing of this cover that I frequently became tempted to unscrew it and throw it away. Now to be fair I could have replaced the black cover with the included transparent one in the box but it still wouldn’t have solved the issue because I would still have to keep flipping it open every time I wanted to change a setting. I suppose you could probably live with it if you don’t adjust your settings often but it still seems like a really bizarre design decision.

Ease of use

Apart from the previously mentioned screen cover and the somewhat awkward lock button the device is very straightforward to use. It works like all Wismec devices so if you have familiarity with them you will be right at home here. The included manual is thorough and covers all functions and even a new user will get to grips with it quickly.


I cannot honestly fault this device in terms of performance because everything works extremely well. This is not really surprising since the new Wismec chips are seriously good.

I had no issues at all when vaping in Variable Wattage or Temperature Control Mode. The device does a good job at detecting the correct Resistance which can also be locked by the user. Battery life was typical of a single 18650 device with the battery of course being drained much faster when using Temperature Control.

I was not particularly impressed with the included tank. The first reason is that the top cap on the tank which you have to remove to fill it was practically welded on. Another issue with the tank was that it tends to stick to the device so when you come to unscrew it you end up removing the upper section and dumping juice in your lap. The vape it offered was decent and flavour was rather nice with some good cloud production. Since it is included as a part of a starter kit I can be somewhat forgiving but the truth is it does feel rather cheap and not on par with Wismec’s usual offerings.


The RX75 certainly performs well enough but it features some rather odd design decisions that I wasn’t a huge fan of. As someone who owns an extensive amount of mods I like the functions of a mod to be quickly accessible and the RX75 screen cover just felt like constant faff to me.

The included tank was also disappointing although it might be okay if you are lucky enough to get one that doesn’t have the top cap stuck in place. Size is another issue where the RX75 falls down because it has the weight and bulk of a small dual 18650 device but only has a single 18650 battery capacity.

If you received this as a gift then rest assured it will vape just as well as other Wismec devices but for anyone who owns a Reuleaux or an RX200 already then quite frankly I would skip this one because while it bears the Wismec name it is very different to their other devices and you might not actually like the changes. Perhaps if you are a new vaper you might find this device very appealing but it does depend a great deal on personal taste and preference because at the end of the day while I might not especially like it (seriously buy an RX200 instead) there will always be someone out there who will love it.
