Pros:Polycarbonate plate makes for very poppy soundMetal plate is very sturdyGood build qualityLike screwless design although it is a bit hard to take apart the first timeVery beginner friendlyRoom in the budget for modsSounds amazing when you put in the workCons:Isn't really what I would consider "gasket mounted"Knob gets weird after you take it off a couple times (throw some paper towels in it until it sits right again)Lighting options take some researchThis keyboard checks all the boxes I was looking for. It’s 75%, has both wired and wireless connections, and RGB built in. Also has a knob if you’re into that, which I am. I got Akko Lavender Purple switches and Glorious Aura V2 keycaps for the board and they work great.That being said, the software is bad. Windows straight up says there is a trojan virus in it. I was able to run the software on a mac. Not able to change individual light colors. You are able to re-map keys, but it’s a pain. Luckily it does save your settings so you can do it on a mac and it will work with the same settings on your PC.This is the second Feker IK75 I've purchased and they are both really good kits. Bought the first for my son at Christmas because he wanted to build his own kb(I've been building kb for a few years). His build turned out so nice that I bought one to try out to see if I'd like the 75% form factor and was surprised what a good board it is to build. I switched out the metal plate for the PC one. The stock stabs were lubed and we're actually pretty good with no clipping needed, but I had some Durocks laying around, so... Other than that, I did no other modding, installed lubed Purple Panda switched and some nice ABS caps and it's actually a really nice build. Sounds pretty thoccy, looks nice, and is overall fairly well made. Can't really go wrong with this keeb.This keyboard is really solid, they do a lot of the stuff that you would normally have to do yourself for you! There is ample foam preinstalled, and they include a polycarbonate plate that you can easily install yourself. The stock stabs are very nice too and really don't need to be replaced in my opinion. I like how they cut cost by opting not to install cheap keycaps and switches like every other hot swap board on Amazon seems to do. The knob is a little wobbly, and the 2.4GHz connection isn't as strong as the connection in the Royal Kludge board I've been using for the last year or so.I have 7 different layout keyboards, turn out this keyboard layout I use the most for daily gaming and working. For this price you can get gasket mounting, you cannot find it otherwhere else.Two thing this board doing bad are no screw in stabilizers and north facing pcb. If they fix it for next version, it will become perfect for this price point. For now on, keychron V1 still beat this keyboardThis board is really, really great value for the money. I knew I wanted something with a volume knob, but this board came with a lot more unexpectedly nice features. For example, I have a set up with my work laptop docked and my PC next to it. The 2.4ghz receiver makes it really to wireless use my work set up and when I need to switch to my PC, I just plug it in through USB-C (I don't really mess the with Bluetooth because of latency issues with my PC). I don't really mess with RGB too much but there a lot of different color combos if you're into it.I put some manufacture-lubed AKKO Green Tea Switches on the board and this thing is milky! Didn't put any other after-market mods on it. I didn't even do the PE foam mod because it came with foam already between the PCB and the metal plate (though I switched to the Polycarbonate plate). The case itself is plastic, but it's $90, wasn't expecting much more.Check out Consumer Tech Review's review on the board if you need some more background on the board.Also if you need the manual just google a PDF version of it.You can tell the company who built this board is in tune with the hobbyist side of mechanical keyboards. It has many sought after features of boards well above its price range. Good sound, good quality, fairly easy to work with if you're looking to mod it (Although taking it apart initially is not easy, as its clip on vs screws). I have quite a few builds ranging from $100-$600, and I was pleasantly surprised with the end result.The reason I gave it 4 stars is because one of the PCB screws was stripped upon arrival, so I was not able to change to the polycarbonate plate. A bit disappointing, but probably a rare occurrence. Overall I would recommend pulling the trigger on this if you're looking for a solid budget build.I've really enjoyed this keyboard a lot with some gateron milky yellows and a set of bulbasaur keycaps I got off etsy with the PC plate. It sounds great, the gasket mounting makes it really easy to open up to tune, and the knob is great.The only problem I've had with it is that the software defaults back to Chinese every time it updates and can be really slow sometimes
