If you don't have an EC Evo I would suggest the EC2 Evo over the AM because the Evo performs better than the AM especially at the lowest setting. It is shorter though.
I was testing the AM and it appears to have higher CPI than the box states. The steps are more like 450 x 1.37, 900 x 1.37, 1800 x 1.37. I get 2.5m/s at both 1000Hz and 500Hz tested at 600 CPI. I think the lens is HIGHER in magnification or maybe the hight of the lens is different. Either way the LOD seems lower than the EC Evo and if I remember correctly it has higher CPI than the Evo. I don't have my EC2 Evo right now to double check, I only have my EC2 original.
I am not really happy with this mouse compared to the EC1/2 Evos I bought.
If your a higher sensitivity player that uses a black mouse pad then you may want to buy this mouse. If you use any mouse pads that are not pure black do not buy this mouse. If you are the kind of person that will open it up and mess around with the internals you might want this as a modable mouse. The mod I would suggest is to get an original Avago lens and fit it to the AM. If you don't like Huano switches you can then change them with Omrons. If you do this I think the mouse will be great compared to the stock state. Those people who want to try to put a 3090 into a Intellimouse use the EC Evo's PCB over the AM's.
I will end up changing the lens on this mouse when I can get one, I will leave the switches.
So anyone know where I can get Avago lenses cheap and easily? I have a few Zowies to save.
Edit: I more throughly tested the AM after I cleaned the lens and the claimed 1150 and 2300 steps are about 1.38 times the native of 900 and 1800. The claimed 450 step is higher at around 508 CPI but not the 450 x 1.37 which I assumed due to the other steps and in game sensitivity.
If only I had my EC2 Evo to compare it to the AM. Have to wait on that and edit again.
