   This is my first mechanical keyboard. Previously my budget was around <3000 but when did some research about mechanical keyboards and came to know about this brand , I was convinced to order this and it has exceeded my expectations! The keyboard is really worth the price expected that you will use it for years (go for hot swappable one as it will allow you to change switches later). Heavy in weight / Subtle and decent color / Strongly built keyboard. I guess you will never find any with this level good quality in India.

   This is the first mechanical keyboard (first keyboard anyway) I’ve bought, so there isn’t any standard/basis for comparison. Originally wanted to get a K6 pro but it wasn’t available then (and even at the point of writing). Decided on K2 pro since it is the next closest and dedicated function keys seemed useful for a slight increase in keyboard space. Using QMK, the entire function row can be mapped to the number row so the difference is minimal (NOTE: I have not mapped it this way). I still prefer the function row but if the k6 pro was available back then, I *might* have gotten that instead.

   After using this keyboard for over 8 months, I can say that this keyboard is great for someone looking for a mechanical keyboard.

   For the period I have used this, there were no issues with keyboard. Bluetooth works without any hassle and so does wired mode. Bt has a greater latency compared to wired mode (90Hz vs 1000Hz polling rate) which is obviously not noticeable on normal non-gaming uses. Gaming on bt, the lag is noticeable and wired mode is preferred if you’re playing online.

   Using bluetooth on linux *may be* a little bit of a hassle; however I found some instructions online on the matter which always works and thus the issue was resolved. Gist of the article: Pair bluetooth device and then connect.

   Battery life is good. You get an extremely long battery life if you’re using the lighting sparsely or not at all (certain lighting modes use lighting minimally; Battery life was long enough for me to forget the recharge duration and sometimes even that it needed to be charged). The LEDS seem decently bright but since I have no basis for comparison, it may or may not be to your liking. Substituting the keyboard for a disco light eats up the battery quite fast but it still lasts for a few days. The keyboard sleep after sometime of inactivity but wakes up fast enough for it to not be annoying.

   I have little idea about switches but the switches did feel a little loud for my taste (Sound however is fine, I think). I ended up swapping the switches for Durock dolphins with switch films for the keys that were used a lot and now it feels sufficiently silent for my use case (The silent keys are a little heavier though).

   Using QMK is fun and sometimes challenging. I have not used QMK a lot but I managed to get a portion of my configurations to work(Caps word and layer led indication). Other parts of my configuration will be implemented some other day when I feel the need for it (and I’m more ready). The QMK documentation is an excellent resource for understanding and using QMK. The keychron discord is also very helpful. Using VIA is fine and useful if you want quick changes with a GUI but QMK is more powerful (VIA: conveience, QMK: power).
   I have only used VIA for quick remaps for testing the keyboard the month I bought it so I won’t be commenting much about VIA except that it works.

   Some spots on the keys are becoming shiny due to wear(most noticeable is the spacebar) but it isn’t much visible unless looking at from a specific angle. The legends on the keycaps are perfectly fine with no signs of wear.

   Tl;dr: Great keyboard. Would definitely recommend for a first mechanical keyboard. No quality issues experienced and nothing to complain about (so far at least).
