Pros: when it works, it's good weight, size and buttons are awesomely placed.
Cons: 5 years ownership total. Used for 3. Had several issues with it. Mouse button clicking twice instead of 1 by itself on random occasions. The tracking skipping. The tracking lagging. The customer support telling me to screw myself regardless of all the issues. After I shipped it to them once, and they return the same mice with the same problems and washed their hands.
Summary: I purchased this mouse once and it had a lot of issues. The mouse would always move even when you where not touching it. It would also have a downward drag making it very difficult to aim the mouse correctly. I returned the mouse because I thought maybe it was just a defective one. I ordered another one and sure enough, it had still had problems. This time it was the wireless mode.
Summary: Please do not purchase this mouse! I was extremely disappointed in the overall experience for this mouse. The mouse feels great in the hand and the wireless feature works flawlessly however it was over-shadowed by the terrible drivers needed to use this mouse. Whenever you unplug the mouse and plug it back in it takes up to 5 minutes for the software to recognize and reconfigure your mouse to your personal settings, other wise you're stuck with basic drivers until the...
Summary: I bought this mouse to do some gaming on my MacBook Pro retina, and it turns out the drivers for the wireless receiver/charger are so poorly written that my Mac crashes everytime it wakes up with the device plugged in.
Summary: It's a really nice mouse, BUT I have random disconnects with it in wireless mode, after that I have to disconnect and reconnect the dock, and the mouse loses my DPI Configuration, It goes to full sensibility, and takes around 10 or 15 minutes to get my configuration from the Razer Synapse for work good again (or I have to disconnect and reconnect many times). I'm really disappointed, It's an expensive mouse, and should work fine.
Summary: I bought this with a new PC build and going on 2 months now, I'm on my 3rd mouse. I bought it for the choice to go wired or wireless and the simplicity of the button setup, weight and shape for my hand. All of these aspects, it does VERY well in (So I gave it one star) It's expensive. Other mice in this category run 20 or so dollars less, but it's Razer, so there's that.
Summary: Pros: It's has pretty lights Comfortable in the hand Nice charging dock with pretty lights (which does not work) Ability to latch usb cable to front of mouse to use as a wired mouse, in case charge runs out. Cons: Battery life is about 1 to 2 hours, so you have to use it as a wired mouse. Battery completely died after about 2 months of use. Purchased a $20 replacement battery, which either arrived DOA, or something in the mouse is malfunctioning.
Summary: I have latest firmware, no aid. It has connectivity issues, sudden drops. Very annoying, not expected at THIS price. Packing is horrid. Way too many plastic, not Ecco at all. I wish they made simple small pack and spent more money on engineers.
Summary: My logitech MX finally died, and I thought that Razer would be a good alternative, since I'd had a pair Logitech headphones not too long ago, and the quality isn't there. Do not buy this. I've already dropped mine in a box for a return. The construction of the mouse is cheap. I'm sure the ostentatious packaging it comes in costs more to produce than the actual mouse. The plastic is flimsy and cheep-feeling.
