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

2.4 GHz adapter works amazing. Great response, a smidge touchy for regular everyday stuff. Bluetooth is just ok. Had some issues with signal issues to my HP zenbook but need to test with other devices. Feels great and awesome battery life. Good portable everyday mouse.

This may be the best travel mouse I have ever used. Heavy, solid, pairs easily and never drops connection with either the wifi or BT. Its weight is primarily affected by the 2 AA batteries carried internally. Some opinions on weight: If you game or do basic office work, you will never be more accurate than with a heavy mouse than with a light one. Why? It simply gives your brain a starting point and allows you to calculate an exact end point because you have a known weight with which you are moving allowing you to end up in the exact location that you intend to be at the final destination. Headshots are much easier with such a tool. There is one advantage with a light mouse however in that you will move much more quickly from the start but you will trade accuracy as a result for that twitch factor, so take your pick. Lets just say you will never be accused of cheating if you use a light mouse because your movements will be more erratic and far less accurate. In addition, if you game with a light mouse, expect to hate the transition to a heavy mouse for a while until you get used to it. Only when you start seeing some of the incredible shots you pull off will you start to appreciate it. Pros: -Heavy; -Solid construction; -Smooth accurate glide surface; -Easy to pair with solid non-dropping connections; -Works equally well on Linux as it does on Windows without hunting for drivers. -Includes both wireless and BT so it works on anything; -Very comfortable fit for a small mouse. Cons: -You will hate this mouse if you have big hands so dont buy it; -You wont like it if you prefer a light mouse; -Razer software wants to link to a real person / email address before you can use it. I have not tried to load it yet so I dont know if the current version is still doing that but it is almost a guarantee; -Marketing preys on Consumers who dont understand DPI and I hate that about mice manufacturers as they all do it these days. I better elaborate on the last one. DPI on this mouse is an astronomical 7200 DPI (note this is not the industry highest either). What does that mean exactly? Well, it stands for Dots Per Inch. To put that into perspective on why you really dont need it, you might first want to understand that mice that were 600 DPI back in the 90s and 2000s and they still work perfectly fine and were like that for years. That is all you could ever buy until Razer changed that game with a product called the Boomslang mouse. Matter of fact, I think I still have a Boomslang around here somewhere, but this is off subject and you can probably read that history yourself. To make this easy, DPI of 7200 means in exactly 1 inch of travel, your mouse has the resolution to move 7200 dots worth of travel. This is simple enough. Now lets analyze your monitor. The majority of monitors are still 1080p which means you have 1920 dots across. If you do a literal translation of this mouse to your desktop screen at 7200 DPI, that means your mouse would traverse from left to right of your entire screen 3.75x is the space of 1 inch. If we were moving vertically, you would traverse the entire screen 6.67x!!! Even if you have a modern 4K monitor, 1 inch of travel would mean you would still be traversing the monitor nearly 2 times! If you are starting to visualize this, this mouse would be pretty much unusable if it were not dampened by software and no longer running at its native resolution. When razer released its Boomslang way back when, if you didnt dampen its 2,000 DPI, it was already unusable right out of the box. These days, it seems to be expected that manufacturers are doing this and Windows will dampen it right out of the box for you. Lets just say while your mouse may be 7200 DPI capable, you are not really using that capability. The point of all this is simple... Marketing hype for these super high resolutions is just that, hype. You are not going to be a better gamer if this thing was 2,000 DPI or 20,000 DPI. You cannot possibly use these resolutions effectively. With that said, the way the mouse feels and moves physically means everything and that is what will win the day, and boy does this mouse feel right when moving it. I hope all this makes sense. What I have not tried: I have not loaded the Razer software which allows you to tweak the mouse like polling rate and DPI. I might load it to check out what the latest tools looks like but there is no need to load anything special to make this mouse work and I likely wont use the tools after the initial look. Update 1/19/19: Mouse has a major con.... My wife liked it so much she took it. Just had to buy another one to replace it. In the approximately year I have owned it, I have never had a single disconnect / dropped signal as mentioned here by other reviewers. My only thought is that there is a problem with the bluetooth on their laptop, a problem with drivers on their laptop, the mouse entered some sort of sleep state which it will do after a certain amount of inactivity, or they got a bad mouse. Note that I have never used the official Razer drivers either so it could be a problem with Rzer software that I am not aware of.

I used notebook/portable mouses from Microsoft (specifically some variation on this one https://www.amazon.com/Microsoft-Wireless-Mobile-Mouse-4000/dp/B002DPUUL4/ref=sr_1_3?dchild=1&keywords=microsoft+mouse&qid=1602543672&sr=8-3) for years. That form factor became comfortable (average to slightly above average sized hands) and every mouse Ive used since has felt too big and flat for my hand to rest the way I was used to. But sadly, that mouse itself has become too slow/inaccurate for the work I do as a designer, and the casual gaming I do in my leisure time. This mouse is a bit flatter than that Microsoft mouse, but the build quality is 100x better, and the form factor absolutely works. No problems so far either, Ive heard the dongle can break, but on my setup the dongle goes in, and doesnt need to come out, so Im good! If it breaks, Ill adjust my score!

I have 2 of these now - one for me and another for a family member. My family member’s mouse jumps around at times and I’m not sure why. Her mouse pad design has lines that may be causing this, but I have the same mouse pad and have had no issues. Otherwise, it’s a great mouse but the battery drains fast if you don’t turn it off when the computer is off.

So far so good, have had a few issues with it not wanting to wake from a sleep state which causes a second of delay and no mouse input. Im sure there is a setting to turn that off but i have yet to find it. The mouse is a little smaller than i expected and also the battery life is not as good as i was hoping for. So far the battery has died once and iv only had it a few weeks. Quality is on par with the rest of the razer products.

I bought this 1/2 a year ago in Like New condition to save some money and havent had -ANY- problems until now. My scroll click is acting up and you better believe that if I cant fix it Im about to buy another one, in New condition this time. Likes: - Its tiny! However I have tiny girl hands. At my job most people use Medium or Large gloves, whereas they special ordered Small gloves just for me (and in my case X-Small fits better but those werent available). IF YOU DO NOT HAVE SMALL HANDS YOU MIGHT FIND THIS MOUSE UNCOMFORTABLE. Do NOT take it out on Razer; the Atheris is clearly marketed as a Notebook mouse. Meaning it is portable and wireless. Exactly what I wanted! - Battery life is bananas. Sometimes my batteries die in the middle of a gaming session because I forgot that the batteries need to be changed! I tend to get a few months out of a fresh pair. In fact I regularly swap the batteries out of my milk frother at around 30% (because it doesnt perform optimally) and use them in my mouse until they die as there is no performance loss. - 2.4 GHz is smooth. If I switch to Bluetooth the cursor sometimes gets choppy due to my other devices interfering with the signal (Cellphone, Xbox One controller, etc). My Bluetooth dongle is 1 foot away. The Razer dongle is about 2 feet away from the mouse and I usually have my phone sitting between the two. Ive never experienced any lag. - Ergonomic and stylish! It is extremely comfortable for my palm grip. If you have larger hands (and by that I mean normal people sized hands lol) Fingertip or Claw grip should work great! The buttons arent ambidextrous which is too bad for lefties, but thems the breaks! Dislikes: - No Chroma. :( This isnt a con, just a personal preference. Id love this even more if it synced up with my other peripherals. But I know a lot of people dont like the lighting and disable it soooo.. it is what it is. - Thats it!

I love it. It fits perfectly in my hand, left or right.

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.

Great wireless mouse, razor synapse is it’s only downside, if you get stuttering or jumps , reset the mouse and re-install synapse, set the polling rate to 500hz or lower, and lift off settings to 10.
