I just picked my g class up yesterday and all I can say is WOW, both negative and positively.
I have used an M class and a Q class. Im somewhat familar with Yihi products
The negatives, which are REALLY negative!
The negatives are really bad. Everything related to UI and setup are the worst I have ever seen on a device of this price point. Getting the driver installed was a PITA. It kept telling me I had an atomizer detected. Getting it to detect my device was spotty. Getting the bluetooth setup so I had the ability to customize on my phone screen is setup poorly. Oh, and the latest firmware install? It refused to copy the entire firmware file over leaving me with an unusable device until I could get it to copy the entire firmware file over. Thankfully, it doesnt brick the device with a partial copy.
The UI on the device is terrible. For those that think they will get it because they are techy people, trust me, it makes no sense, I still dont understand it. Pushing left does one thing, pushing right does something completely different (youd think left and right would navigate around the main screen and up and down would change values - or, pushing the joystick in would select a value and left and right would change the values). However, I think the engineers at Yihi are drunk. I think they are
vaping moonshine.
On the UI side of things, even the guys in the vape store had trouble getting this thing in temp control mode. It doesnt TELL you its in temp control, it wont tell you why it goes back into wattage mode, it is not helpful. Turns out, you need to lock your resistance by holding the stick in for 5 seconds, then some bizarre button combinations to switch to jules mode (if it says W after the big number, you are in wattage, if theres a J, its in temp control).
Installing the most current firmware puts your device in bypass mode. Try to figure out how to get out of bypass mode? Why is this enabled by default? No one knows.
The app to control it on your phone? You have to side load it? What? Oh, you want to find the app? Yea, its under the Q class, a completely different device.
The screen is terribly small. The fonts are super tiny. The background colours in the menu make the text even harder to read.
The pros are on the opposite side of the spectrum.
My setup - an aromamizer dual coil stainless steel alien clapton four x 28g claptons wrapped with a single 36g clapton. Resistance reads at exactly .01 ohms.
I have seen alot of
reviews on this product and battery life gets a 1 sentence mention. The battery life is worth mentioning and explaining. On an RX300, a four battery device (and huge), Id leave a 12 hour work shift with 30% battery. On the G class, a two battery device, I left a 12 hour work shift with the same 30% battery left. Think about that for a minute. The G class is using half the battery of the RX300. This means a 2 battery device is an all day device. I ran in temp control most of the day on about the most intense coil setup on the market today and this thing still lasted me all day. Compare that to the Q class battery life. Actually dont, the Q class battery life is awful. AWFUL.
Are you listening Evolv? Your
dna chips need some work in this department. I have a Triade with a DNA 250 chip in it and it barely makes it through a day.
Performance is amazing. Once you can actually get your firmware updated and get your settings in, I have never seen temp control actually work, yes, even Evolv has failed me in this regard. The amazing part is, temp control actually just works, once you can get it into TC mode. It isnt finicky. It doesnt just stop working for some reason. It just works. Thats how it should work. Sad to say that I have to even bother typing this paragraph in because jeeze, that is kind of how TC should work.
Did I mention 2 amp USB C charging? Evolv? Are you paying attention?
I am by no means an Evolv fan, nor am I a Yihi fan. They both fail in the UI department. It is time for Evolv and Yihi to open source their software and let the community do the UI, implement features, and fix bugs. Yes, I know Evolv is doing the 75C. However, the screen is too small, their is not enough storage space on the board for multiple themes (memory is cheap, Evolv is selling the boards for $80-$100 - put a gb of storage on there so people can store the setup software and multiple themes, charge a $1 more, no one will care).
The reason to buy this device is simple. Good performance, good battery life, USB charging, feels good in the hand. It feels REALLY good in the hand. Its not giant. Its just right.
Just be prepared to spend hours getting it setup and configured and then prepare to spend even more hours trying to change everything should you put another atomizer on it.
