Sigelei reached out to me on my facebook page and asked if I would be interested in reviewing some of their products after they saw my other reviews on the forum, and I was very happy to. I went past the Sigelei stall at vapecon and had a chat with the guys there as well. After not seeing much Sigelei products in the past years, I was really interested to hear that they are trying hard to make a good comeback (not that they left but I think in SA they were a little behind the more popular brands) and I am happy to say that it seems they are coming back with a bang! Hold on t Item Name : Snowwolf MFeng UX 200W Manufacturer: Sigelei Website: https: http://store.sigelei.com/Mod/Snowwolf-Mfeng-UX-Mod Cost: $70 / R1021 (Converted from $ estimate) ***DISCLAIMER*** This device was supplied to me by Allen from Sigelei Technologies for the purpose of reviewing the product for them and providing my personal feedback and opinion of this device. These opinions are my own and can differ from vaper to vaper. What’s inside the box you ask? 1 x MFeng UX Mod 1 x USB Cable 1 x User Manual 1 x Warranty Card 1 x QC Pass card Technical specifications are also important, so here they are: Dimensions: 91.5mm x 49mm x 30mm Display: 1.3” TFT Material: Zinc Alloy Battery: 2 x 18650 Batteries (Not included) Power Range: 5.0W - 200W Temp Range: 100C – 300C / 200F to 570F Voltage Input: 6.4V – 8.4V Voltage Output: 1.0V – 7.5V Resistance Range: 0.05-3.00Ohm Modes: Power / SS(304/316/317) / Ti1 / Ni200 / TCR Max Current: 40A Charging Current: 2.5A Chipset: Integrated Chip Set Exploded View: Looks and feel: Let’s start off with the aesthetics of this device. I can confidently say that this device is built well, you can feel it and see it in the way this device is put together. The paint work is thick and not thinly sprayed but rather looks like enamel or powder coated which makes me believe you won’t be having major paint issues here except for possible scratches. When it comes to the buttons, they are all good quality without any movement or rattle and sits firmly in place. The fire button is runs down the side of the device and provides a dual action fire button, meaning it swivels and can fire when pressed on the top or the bottom. The fire button looks like an elegant name plaque in silver and gloss black that has snowwolf written on. On the inside of the device, you can see the serial number engraved on one of the magnets and if you look at a slight angle, you will find an autograph which I take is the designers autograph or initial and surname which I cannot make out lol. Menu’s and access: To access the device menu, you press the two buttons below the screen which is used to increase and decrease the power settings but is also used to navigate up and down in the menu. Once inside the menu, the fire button will act as the select or confirm button. Note: I am unable to capture the colors of the screen for some reason, but it is full color, Just looks black and white on the pics. Features: As with most regulated mods, the Mfeng has power mode and temp control mode which is really easy to setup and use. I don’t use temp control ever so won’t be reviewing this part but will talk about the power mode and its settings. The device seems to be set to 40W as default. When attaching a tank to the device, the device will automatically read the resistance of the coil and then set the recommended wattage. I find this a little annoying as it doesn’t have an option to disable and it will default to 40w or auto read if you remove and reinstall the atty. Power and Preheat Mode: Offering the user up to 200W in power and a fire rate at 0.005sec, it really works great. If it is one thing I hate is mods that take long to heat the coils but this is where preheat is one of my favorite functions. When selecting the Power mode, there isn’t any customizable settings to change for the user, when selected the menu returns to the home screen. The only setting you can change is the Preheat function which is super easy. Entering the preheat mode menu, you can choose between 4 modes (Soft/Normal/Hard/User). When selecting User mode, you can adjust the preheat power to your preferred range, I chose 90W while testing and then you can set the time which preheat will be active in seconds. I set this to 1 second. When you fire the device, it will fire at 90W for 1 second and then fire at the user setting which was 70W as I set it. This function works great and helps give that hard hit at the beginning of each drag. Child Lock This is a nifty little feature having a PIN code which makes it impossible for someone without the code to use the device. You set a 3-digit pin as per your preference. You will then be able to lock the device with 3 clicks. To unlock is 3 clicks and you need to enter the pin code. This isn’t something I would use daily but rather on the out and about. Protection: The MFeng provides 8 protections to the user So, what do I think about this device? Let’s get down to the nitty gritty! The want to hears and the not’s! My Pro's Simplistic user menu, easy to use and understand. Extremely well built and feels solid, Quality color screen which is easy to read with brightness adjustment. Child lock with 3-digit pin feature Preheat function, which is super easy to setup with 3 modes or a custom mode. 0.005sec firing speed The device overall looks good with lots of detail and feels like a HE mod. Spring loaded 510 PIN Decent Paint, almost looks like its powder coated Double fire button (Fire on bottom or top for user preference) Offers good battery life and doesnt eat through batteries My Cons's Seems like a lot but its not that bad... No battery ribbon to pull the batteries, I love these it just makes it so much easier than having to pull it with your nails. Front metal plate is sensitive to scratching, not even sure how mine got a scratch in one day! Its Heavy, but like solid heavy (Might be a pro or a con) When removing the atty, the device scans the resistance and auto adjusts the Watts and does not give an option to keep your previous setting, this is irritating! Display a little too simple, only shows the voltage details in TCR mode and not power mode. In power mode it only displays the power and the resistance. The following Colors are available: My Verdict: Although it’s a little heavy, its well built and looks modern and elegant. The user menu is probably the easiest to use and understand and the layout is also simplistic but looks great. One thing I am worried about is the metal face plate becoming all scratched up in a short amount. Other than that, the device utilizes the battery power great and provides great battery life. Overall, it’s a really good quality mod with no real or major issues. The looks might not be for everyone, but I think its different and a well-designed mod. Would I buy one with my own hard-earned cash? I probably would if I’m in the market for a new fancy and different looking vape. So there you guys have it, I think Sigelei is back with an Bang!!!
