I like the Zowie AM, have had no issues with tracking or input so I can't complain about it not doing its job. The shape itself, for my hand size allows me to use a variety of different grips comfortably. I can switch it up at an instant and not feel like I have to get used to it. Gets dirty though, but 9/10 would buy again.

I have an AM, I love it and I cannot fault it at all, I've had it for a year and a half, never used one mouse for that long before. But for some reason I can't help but feel like I could be a better gamer with the FK.

I love my EC1 eVo. I was originally going to go for the FK, but coming from years of using the MX518 and G400, I was kind of put off by the ambidextrous design so I went for the EC1.

I hated the feel of the mouse at first, but I got used to it within a week or two.

Are the side buttons for the AM in a comfortable position for a push to talk key?

seems like the G502 has a better sensor than any mouse now available (zowie mice included), besides that, its gimmicky look (useless buttons and everything) and its price are big problems for a lot of players, anyway the best zowie for you would probably be the EC since you've had only dextrous mice (g500/s g502), but as i said in another post on this forum, there's probably a refresh for the EC series coming out, by refresh i mean they'll probably mount the new 3310 (Fk1's sensor) which is the best sensor zowie used on its mice this far, on new ECs, this means no odd CPI steps anymore, lower LOD, faster in terms of m/s

Really, even lower LOD ? I have an EC1 evo on a SS heavy pad. If it would be even lower, it would be pretty much unusable.

Like it was expected, the LOD is very low. I love it, and everyone who liked the previous Zowies will feel right at home too. It is a bit higher than with my older IR-LED FK’14, but still very low. It still tracks at one CD but not at two. The old FK didn't even track at one CD height.

There is a novelty with the FK1 too. As many on this forum already know the 3310 allows for LOD to be customised. But normally you would need Software to adjust it to your liking. As Zowies philosophy is to not have software but change everything on the mouse directly this seems to be impossible on Zowies. But apparently it’s not.

There are methods to adjust LOD on the FK1 similar to how you change the polling rate on it.

The standard LOD out of the box is adjusted for cloth pads to be around 1.5 - 1.8 mm. However this would mean a higher LOD on a plastic pad (2.2 - 2.4 mm). To enable “plastic mouse pad mode” you have to hold Button 4 and Button 2 (back button on the side and right mouse button) while plugging the FK1 in. This causes the LOD to be around 1.5 - 1.8 mm on a plastic mouse pad (and around 1 mm on a cloth mouse pad)

To switch back to “cloth mouse pad mode” you have to plug it in while holding Button 4 and Button 1 (back button on the side and left mouse button).

Now there is also the so called “original mode”. This sets the LOD to be on a standard level and therefore should optimize the mouse compatibility for players with special material mousepads. It will have higher LOD than all other settings. So this is useful for those players who prefer a higher LOD (looking at you Dontspamme). You get the “original mode” by holding Button 4, 1 and 2 at the same time while plugging the FK1 in.

After setting the LOD once you don’t have to set it again every time you plug in the mouse, similar to the polling rate. I think it’s very nice that Zowie implemented a way to adjust LOD with the FK1 without software. You might not be able to finetune, but I think “low” and “high” LOD should be fine for most players anyway.

My experience with the modes:

Cloth mode on Qck+: 1 CD
Plastic mode on Qck+: did not track at 1 CD hight
Original mode: 2 CD

Only with original mode would the FK track on white paper.

Actually isn't lower but it's adjustable
