Razer Atheris Ambidextrous Wireless Mouse: 7200 DPI Optical Sensor - 350 Hr Battery Life - USB Wireless Receiver & Bluetooth Connection - Classic Black

It works but not as advertised. The 1000hz polling rate only applies if you use the dongle. If you connect via bluetooth, you do not have the option of polling higher than 250hz. Bluetooth was the entire reason I got this thing though. So if I have to use wifi anyway, I may as well get a better mouse. Its not awful. But the batteries are not rechargeable. It only has 5 buttons total. And it is really small. If you have big hands, using this mouse will be a problem. I have average sized hands (well...for my size...Im 62) and for me, this feels really (uncomfortably) tiny. Like, even doing work with it ia awkward...gaming on it would be even more so. If all you want is a basic mouse that is portable and has bluetooth capability, this is probably fine. But $50 seems a little steep for a basic mouse like this. There is really nothing that special about it. No LED lighting, limited buttons, no high polling rate. I ended up returning it. EDIT - I removed the part about Wifi drops. Apparently this is an issue with all bluetooth mice. You can solve it by connecting to wifi at 5ghz (Bluetooth uses part of the 2.4ghz spectrum), and also changing laptop Bluetooth power settings so that they are on preformance all the time (many laptops are configured to try to save power on Bluetooth, but you can override it in settings).

Great to see a good gaming mouse in a small size. 2xAA is heavy - use lithium batteries, they are much lighter. Having to sign up with my email to change DPI settings is absolutely ridiculous.

connects easily and the batteries last so much longer than cheaper brands

On both Bluetooth and wireless USB I have to keep my laptop in direct line-of-sight to the mouse, otherwise, the tracking is choppy. I have a dock at work that sits on my left putting my keyboard between the laptop and mouse. Im right handed. I had to rearrange my desk to have my laptop to my right with nothing between in order to get smooth tracking. That aside, I usually only buy wired mice because I dont want to futs with charging or batteries. This isnt an issue with this one. It has a great battery life! Im still on the first set of batteries and Ive used this for 8 hours a day 6 days a week for about 2 months now. I also dont turn it off at the end of the day so the sleep mode works great! The wake up time is almost instant so I dont have to shake the thing awake either. Id recommend this to anyone that needs a small travel mouse as long as they dont mind rearranging their desk to keep the signal strength. Though, Im sure this isnt an issue for the majority.

The only reason I dont give it a 5 star is the product and company are slowly dropping support for Mac. This mouse is responsive, accurate, and comfortable. It makes a great replacement for the Logitech m510 which was a disappointment of a mouse. For work and games I need 5 mouse buttons. This mouse has 5 buttons and customization options that allows for programming not just commands but also batch commands. Which was intuitive to setup and very useful for work. If I could ask more out of Razor it would be to include gesture support which this model lacks. Update: Still working great except it no longer works on MAC :(

The mouse is much smaller than I expected. I have large hands and its a little uncomfortable to use. So thats not a terrible thing, unless you are large featured like me. Otherwise its a great mouse, no complaints.

good wireless mouse, with good battery life( come with 2 aa energizer max batteries, I replaced with 2 energizer lithium aa) can hold a longtime. the first 2 aa energizer max hold about 300 hours of use by 100 polling rate( use more power) via 2.4Ghz usb. my laptop also razer so it come with the Synapse can customize all the settings with out download anything.

Not a lot of lag with bluetooth that can be a thing for the cheaper mice and the scroll wheel feels proper. I dont like the slightly heavier click of the buttons, but this is really not a flaw except that I prefer a very light click. Build quality feels pretty solid

So far pretty happy with this mouse. It is rather small but comfortable, ideal for use as a second mouse to be used for trips, which is what I bought it for.

How good is this mouse? I bought another one just in case Razer discontinues this one, so Ill have a backup. Perfect setup for a quality wireless mouse. Bluetooth band and 2.4ghz band means you can (technically) pick your frequency in case youre in a hotel thats flooded with 2.4 ghz. No problems, no issues, dual functionality.
