Pros: I have purchased from a lot of companies, a lot of different peripheral devices.

Gamdias won me over with the Zeus and Hermes, which I use. The Apollo is what my son uses. It is a very slick mouse, adjustable, RGB control via Hera software, adjustable polling rates.

Cons: The two side buttons are oriented in an awkward spot, great for left handed players as well.

Other Thoughts: Button placement, why ambi? Probably by desing, but for some of the mice they seem to largely be oriented this way.

It is otherwise a fantastic little mouse especially for the price.

Pros: on sale its a great deal for a mouse with some gaming to it.

Cons: light weight, small, the 4 and 5 buttons are too far back to enjoy using them.
Plus dont try to remap them.. the software sucks ...
over all nice travel game mouse for simple gaming but not worth full price not really worth the sale price.

Other Thoughts: NOT WORTH THE MONEY EVEN ON SALE..

Returning it for another mouse !

Pros: The mouse is great for me even with big hands, honestly the software was good. The mouse could have been a little bigger but it was easy to adjust to.

Cons: The mouse software did have one hiccup, that was that I couldn't bind the mouse to a common MOUSE-5/6 and I had to bind it to numpad-0 and numpad-. for the secondary mouse buttons. The right mouse button would be great for lefties but I wish that the buttons were higher forward so that they are easier to press.

Other Thoughts: The mouse is great for a laptop too, because the back half can come off

Pros: Was super cheap
Unique look
Decent response on some light gaming.
Cable length is good.

Cons: Cable is hard as a rock.
Far to small even with the little clip on piece for the back and wish was a just a tad more secure.

Other Thoughts: This is the 2nd Gamdias mouse I have purchased and they do run on the small side and very light. No way I would have paid full price for this item but for what I paid Its a good travel or spare mouse to have. If they were just a tad bigger and heavier I would have given it 5 eggs.

Pros: Great design. Back is removable, which is great for fingertip users or to be used as a mobile mouse. Customizable lights are a nice touch.

Cons: Very small and light, cursor motion could be smoother, absolutely terrible software.

Other Thoughts: I picked up this mouse when I built my PC, and chose it based purely on how it looked and how I thought it would fit in my hand. I figured anything I bought would be hit-or-miss just because I was going off of a picture. The mouse itself would be very comfortable for someone with small hands. For me, it was too small, but not uncomfortably so. The back can be removed to make it even smaller, which I think is a cool feature, even though I would never use it.
However, the software provided by Gamdias is absolutely terrible. The first thing you'll notice is that while in the mouse software, the mouse cursor freezes every 3 seconds, then starts working again. Very annoying, and ONLY happens when in the mouse software. But where this mouse really went wrong is the key bindings. I was trying to bind Mouse 4 and Mouse 5 to some keys that I rarely use while gaming; Numpad 1 and 2. Unfortunately, this completely confused the software, and ended up unbinding Mouse 1 and Mouse 2....meaning I could no longer left or right click. If you don't already know, those 2 buttons are pretty important for a mouse. So I deleted the software and the drivers, unplugged the mouse, plugged it back in and had windows reinstall the default drivers. No dice. I then proceeded to try using this mouse on 4 other computers to no avail.
On a side note, I am always extremely careful when changing mouse binds for precisely this reason. Normally it can be fixed, but not this time. I am 100% sure that I did not touch anything having to do with Mouse 1 or Mouse 2, yet they were remapped or erased anyway.
Gamdias customer service is email-only, and not only did I not have time to wait for a reply, but it would have been very difficult using only a keyboard. I took the faster route: drove to my local electronics store and picked up a different mouse.
Normally, I would have contacted Gamdias anyway to see if they could resolve the issue, but after trying out my new Roccat mouse, I don't want to go back.
My advice would be to avoid this mouse at all costs. It's not a bad design, but it feels cheap and the software is terrible. If you like very small and light mice, or are looking for something to carry around with your laptop, this will work for you if you just never touch the software and forget about ever using Mouse 4 or 5. For 99% of people, particularly gamers, get something with a reputation, like Roccat. You don't even necessarily have to spend more money. This mouse was barely worth the price when it worked. The software ended up killing it entirely.

Pros: So smooth, giving me the options to adjust my speeds when going from my FPS games to my MMORPG games. The grip is nice and easy to use, nothing complicated about it. Love the customizable profiles available with their downloadable software.

Cons: Although the grip is nice, I wish it was a little bigger.

Pros: Great for fingertip grip since the back end of the mouse is removable. Just plug and play, optional drivers are available, Solid build quality. No problems so far.

Cons: Wheel click takes more effort compared to other mouses, but I don't use the wheel click that often.
