This kit was well worth the wait from the group buy. Everything in the kit is dead solid and adds together to form a very clever little gasket kit with just about every enthusiast feature you would want. There are no detrimental issues with the board on any level. You are going to get exactly what you think you are going to get and what you get is really great.
On my build, I paired the kit with Drop Phantom Stabs, Gateron Milky Yellow Pros, and NP PBT keycaps. Unfortunately, while the stabs on this board are plate-mounted due to the PCB design, with the stabs listed above, I got a very tight fit. I had to do zero modding to make them sit without a wiggle. The plate has nice, tight tolerances seemingly. As tight as the tolerances on the rest of the kit. I imagine that any half-decent set of stabs would fair well based on my experience.
The acrylic is machined very precisely, and seemingly without any extra scratches or burrs. For being a two-piece it's pretty immaculate with barely a seam to feel on the edges once assembled. The way it's CNC milled along with the foam gaskets allows for a surprising amount of flex even without a fully flexible PCB. Speaking of the PCB, it's a gorgeous white and just looks awesome.
All-together things sound nice and clean, and better than you would expect for the price. Acoustically, the final sound of my build was deeper than expected and to my ears quite pleasant. It's hard to go wrong here if you are in the market for an intermediate kit and the acrylic look. So before I list off my nitpicks with the kit, I just want to stress how awesome this thing is. I love it, and the overall end result far outweighs what will sound like a litany of issues. You don't have much to lose and I'm convinced this is about as good as it gets for value and an acrylic case.
Onto my small niggles with the board. The flex on this board comes from the space created by these small foam gaskets. They do their job well enough, but the foam just isn't as hardy as it needs to be. I made the mistake of putting on the gaskets and getting the board mostly assembled before installing the switches as per Epomaker's assembly video. I DO NOT recommend that you do that. Get your switches installed, maybe even with keycaps before you stick on the gaskets. Otherwise, the force of pushing down on the board while you install things will flatten out the bottom gaskets, they will be ruined, and you will lose that sly flex. An immediate improvement to the design would come from rubber gaskets on the bottom.
Secondly, while the board does have VIA support, it's not as in-depth as expected. At least on my Mac set-up, VIA was not able to recognize the board automatically. You do have to import the layout yourself. You also will not get access to the "Lighting" panel in VIA with this board. The profile it uses is the "FK680 Pro" profile, and while you will get three layers of macros and key options, that's about all you will get. All of the RGB options are preprogrammed and untouchable. There are SO MANY animated lighting setups, colors, and effects. Genuinely it's staggering. The average person will not miss this panel, and will surely find something close enough to what they want. Personally, the only RGB scheme I cared about was an all-white array, and the board just doesn't do solid white. There are some animated variants that use white, but if that is what you want you are out of luck and VIA can't help you. Expect rainbows and only rainbow colors.
Thirdly, the included cable is awful. Practically not even worth including in the box. I doubt it will ever straighten, is very cheap feeling, and I haven't even bothered to use it since it was in such rough shape. Count on using an aftermarket cable to be happy. To be fair, most people assembling kits will be using an alternative cable anyway. Strange inclusion overall.
Lastly, aside from the foam gasket issue the foams in the kit are good enough but have some problems. Expect the foams to have some impressions from shipping that are not going to come out. Mostly, I'm referring to the uniformity of the gasket sheet and the bottom case foam. In my order, the bottom case foam was actually damaged at one end and I had to get a replacement from Epomaker. To their credit, their customer service was incredible and I've since been sent a replacement set of foams without any trouble. I would expect the damage I had to be very rare considering the quality of the rest of the kit.
That seems like a ton of problems, but they are such small issues in the context of the entire kit. I'd probably give it 4 1/2 stars if I could due to these nitpicks, but I'm just going to round up to 5 stars thanks to the great customer service. None of those problems would stop me from encouraging anyone starting down the mechanical keyboard rabbit hole to get this kit.
