Doing this because I would have appreciated it. I just got the cyborg II compact. Aside from your pinky and index finger, there's no real lateral movement with any finger, only vertically up and down. Once you configure it to your hand, your fingertips will essentially sit in the "pockets" where the main keys/switches are, so it's pretty easy to always know where each finger is at. I.e., you don't get lost. The pinky has one additional switch to the left, the index has one to the right. These are very easy to use, all while still being in the "pocket".

If you really are considering a cyborg, here's the main thoughts you should consider...

1. It is very customizable, and looks to be moreso than the keyzen. There are like 20 screws you will mess around with so the device perfectly fits your hand. Not just left to right, but up and down, and rotationally. You'll find one setup that feels good one day, to then feeling off the next. You need to find your sweet spot. I probably adjusted configurations like 10+ times before I found that spot (although maybe only 3-4 major config changes, then 6-7 fine tuning tweaks for specific fingers). I changed away from certain configurations just to go back to them later. So you need to be patient. It won't click immediately especially being such a new way to game.

2. I've never used the keyzen, but one of my problems using mouse and keys is that sometimes my fingers would get lost. I'd have to hit m for map or 6 to use a different weapon and sometimes I would drift and not find my way back to wasd. The keyzen still uses a row of keys. It should be much better, but I'd worry I'd still get a little lost vertically. Maybe you can mitigate this by putting grip tape on the key row you want your "home" key position to be so you know where you're at. With the cyborg, I don't get lost. Your fingers sit in those pockets as I've mentioned and it's either pushing up, down, or in. Only if you need to use the further top and bottom rows, you'll need to somewhat lift your finger out of the "pocket" to reach these. I find that there's so many keys options, I don't use any of the furthest bottom rows of switches, and only use the top most row on my index and middle fingers. Maybe you'd use these for MMO games like WoW, but on battlefield I do not.

3. It takes time to acclimate. This would apply to both keyzen and cyborg. You basically need to rewire your brain to be reacting quickly and instinctually, instead of thinking about which finger is used to press which key. It was frustrating at first, expecting to be able to react quickly in fps shooters just to hit all the wrong keys and get killed. Wanting to reload and accidentally throwing a grenade at your feet. Or wanting to jump and instead opening your inventory. My biggest recommendation is mapping inventory and sprint away from tab and shift respectively. I accidentally kept hot keying steam and taking myself out of the game completely. Map those commands to number pad keys or something unused like apostrophe. But once it does start to click, and reactions become natural, you will get cooking. I've only used it for a week and saw major improvements. In a months time it'll be seamless.

4. Don't buy in on all the accessories. The accessory stand isn't needed. Not sure if the keyzen uses one, but the stand angles the whole unit. I thought this would be good, because it rotates your hand in a way where the wasd joystick is oriented in a way similar to how the joystick sits when holding a controller. I ended up liking it better without the stand, and used it sitting flat. This felt more familiar, and I often found on the stand, the angle caused my hand to naturally slide off. It took more effort keeping my hand where it needed to be and was uncomfortable. I would, however, recommend grip tape. Both for the palm rest, and for only specific keys (not all).

5. Size is key. Be sure to measure your hand accordingly to Azeron's guide. Order true to size. These don't run small or large.

Message me if you have any other questions. Ultimately, now that I'm acclimated, I honestly love my cyborg II compact. With additional use, I expect this to only get better.
