RazerBasilisk Ultimate HyperSpeed Wireless Gaming Mouse: Fastest Gaming Mouse Switch - 20K DPI Optical Sensor - Chroma RGB Lighting - 11 Programmable Buttons - 100 Hr Battery - Classic Black

I ordered this mouse in as it was the same design as the G502 that I very much enjoyed, but I wanted to keep my peripherals matched with my other Razer products, as well as my recent experience with the "updated" Logitech G Hub app was VERY frustrating and not enjoyable. I use this both for work and play at home for many games.The design itself is great and feels very nice to use with my preferred fingertip/claw grip. The biggest complaints about the mouse fall into this field for me though as I very much miss the 2 buttons on the left mouse button that are present in the G502, but are missing in this rendition, however this is not to be faulted against Razer as that is a different mouse, just something I'd love to see. The other complaint is the removable thumb paddle which is very short and difficult to reach without readjusting your grip. The last minor complaint is that the underside compartment where the USB dongle can be stored is a very cheap plastic door that I can see breaking or becoming lost after extended use. It would have been nice to see a more stable hinged or sliding door to house the USB when traveling. Aside from that, the buttons feel responsive and pleasant, and the scroll wheel resistance settings are much more preferred rather than just tactile or free spin. The mouse feels light and sturdy enough that I don't ever find myself thinking it feels cheap, and the grip texture along the sides of the mouse is comfortable and doesn't appear to be wearing off so far.As for the functionality of the mouse, the connection speed and response time is incredible! The mouse reacts as fast as a wired mouse with no hiccups that I've encountered so far. The 20k DPI is ridiculous to say the least and I could never see it being used by myself, but it's fun to see the point scream across my monitors at a mere jostle of the mouse. The battery life of my mouse when I first received it was dismal at best and I was very disappointed to see the battery life drop from ~90% to ~60% after sitting on my desk TURNED OFF for a few hours. I charged to full a few times and was still encountering the issue, so I reached out to Razer Support. They provided me a firmware update file, something that I thought the Synapse app would have done, and after following the instructions to update the mouse, it has been night and day difference! Now my mouse lasts MUCH longer even when left on, with a sleep timer set, while having the RGB brightness set to 30%. Between going from work to home, I use this thing for upwards of 12hrs a day and I can last about 3-4 days before needing to charge.Overall, I very much enjoy this mouse after the Firmware Update was applied and highly recommend it to anyone who enjoys the feel/style of the Logitech G502, but want to try out something different. I would love to compare the wireless G502 to this one, but I don't have the pocket money to do that. So take this review as simply a review of the mouse and G502 "fashion" comparison.

So I am not a gamer, but I absolutely love this mouse.I really like the ergonomically of this device. I love a mouse with a thumb wrist. A lot of the ones you see that have the thumb rest area have tons of buttons on the side and while for some games and some people this is great this one has only a few buttons which serve my purposes perfect. The lighting is nice. It is subtle and it can be somewhat controlled via the mouse, but can definitely be customize with their software. The wireless connectivity works very well. It charges quickly and if you wanted to use it wired the cable that it comes with is extremely nice and looks good plugged up. The buttons feel nice and tactile. The adjustable clutch/tension on the scroll wheel is very nice and easy to adjust on the floor. The adjustable dpi buttons are very nice even for someone who is not gaming as it gives you a little bit more control over the sensitivity of the mouse.I said above my favorite feature is the side buttons negatively I will leave them alone to what they are designed to do. It helps having one that is a back button for Internet browsing. There is a third button that a little rubber cover can be popped off towards the very front of the thumb area And a small metal bar installed to act as a third switch. I use this to toggle a hot key for Ctrl plus alt in order to help me use the Magnifier set up as I am visually impaired. This helps me not have to use keys on the keyboard and we’re just scrolling the Internet. I can zoom in and out while using this macro key and the scroll wheel , it is definitely made life a lot easier and more enjoyable to use my computer.

I have been switching between mice for a while now, and steered clear of wireless mice since my last experience with an older Logitech mouse back in 2014. I was quite happy when I found Mionix, and favoured the Naos 7000 as my daily driver for years until the cable broke. I saw the Castor, and figured that would be a sidestep. It lacked the ergonomics, but had the build quality I loved. At the time, I thought that Mionix with its "perfect sensor" and premium feeling rubberized coating was as high-end as you can get, all without the fancy gamer stuff thrown in.When it came to Razer, I never really thought I would buy another one of their products. I had terrible experiences in the past, with my Tiamat headphones quite literally falling apart from standard use with both the cable fraying and the control box splitting open and exposing the delicate wires inside. Whenever I tested their keyboards during my early mech days around 2015, I thought they lacked the build quality of even cheaper mechs on the market. Many reviews online supported my thoughts that Razer had terrible quality assurance, so I resolved never to buy another of their products ever again. Apparently, that all changed in the past few years.In comes the Razer Basilisk, a very premium feeling wireless mouse that lives up to its claims. Whether I am using it in wireless or wired mode, there is absolutely no input lag and the movements feel silky smooth. If I had any complaint at all, it would be that the 100 hour claim feels a bit overstated. Yes, it will last you all day and the charging time itself is quick. However, after only 6 hours of use from 100% I did notice in Synapse the mouse was already around 74% operating at around 7000DPI with standard polling rates.Beyond that however, the mouse itself feels spectacular. I had previously been using a gel pad for my wrist with the Mionix mice, but it feels entirely unnecessary with the Basilisk. It feels extremely good in the hand, and while a similarly priced Logitech may feel like light plastic, the Basilisk manages to replicate the feeling I got from the Naos or the Castor without the heavy application of rubber.The scroll wheel adjustment is a fantastic feature, and though I wish there were infinite scroll I still enjoy the ability to set the tactility of the clicks or to have no tactile feedback at all.Overall, very amazing mouse.
