Razer Basilisk X HyperSpeed Wireless Gaming Mouse for PC, Bluetooth & 2.4GHz Wireless (Multi-Device), 16K DPI Optical Sensor, Mechanical Switches, 6 Programmable Buttons, 450 Hr Battery, Classic Black

Overall great. Battery life. Precision. Working great over a year later of near daily use.

Bought this mouse about three years ago and loved it so much that I bought it again. The wheel on my first one stopped working well so decided to pick up a new one. Saw that Walmart had it on sale for less than $40 and it's absolutely worth it for that price. I love the feel of the mouse in my hand, and the customizable buttons are very useful. Also having both Bluetooth and a usb for connectivity was also a big reason I bought this mouse. It's a great mouse for general tasks such as browsing the web and casual gaming. If you're looking for a mouse with high gaming performance with low latency then you're probably not considering this mouse anyway, but one that's more expensive and wired. For the average user though who likes to do some light gaming after work I don't think you will find a better wireless mouse with similar features and performance for such a great price.

I like the slick design and feel, the multi speed function is easy to get used to and able to quick switch between. I like the response that the Razer Basilisk has between usb mode or even Bluetooth mode. Very impressed with the technology involved with the development of this mouse

liked the shape and how it hugs the hand (right handed use only though) get it if u prefer a stealthy mouse without rgb make sure to not use cheap batteries, i used cheap ones and they ended up leaking inside and spoiling the mouse this one is a worthy buy till razer keeps charging a premium for a rechargable feature

Supposed to be four High Fiber Instant Oatmeal boxes - Received three and one regular box. Part of an order for twelve boxes, and the other eight boxes were five High Fiber Instant Oatmeal and three Gluten Free boxes. Only got 66% of the order right.

Really good wireless mouse, especially for the price you're paying. However, the main issue I've been having with it that it's always having connection issues. It might be something to do with Razer Synapse, but it'll periodically disconnect for 5 seconds usually three times per session. Really annoying and dissapointing.

Scroll wheel only partial funtions. No scroll up or tilt-wheel left. Clamshell design for battery compartment a poorly engineered thing. A shadow of my earlier Razer mouse this one was supposed to replace. Razer software is inconsistent in performance,in my experiences in-game. Shadey. I'm using an older brand name for my peripherals now. Don't be fooled.

Works great when it does, however the 2.4 GHz connection keeps dropping almost once every 2-3 hours, which is not ideal when gaming. The firmware updater available online does not go past a certain point and it appears that Razer has ceased rolling out updates. Got it on sale for $35 but still not work that given the regular connection issues. I've looked up online and this issues seems to be consistent with that mouse, so very unlikely that I got a defective one.

Both the bluetooth version and the usb version don't connect well to my windows 10. Using the usb it'll disconnect and reconnect a lot and lag all over the screen. Using BT it will lag every once in a while. It's comfortable to hold and looks sleek, but that and the price is all this mouse has got going for it. Not good if you plan to game with it like most would.

I liked the shape and feel of it initially. But it wasn't long before it started to shut itself off. Not after a 5 minute delay, like it's supposed to do, but right while using it. Occasionally, I could get it working again by simply sliding the switch off and on again, but most of the time I had to remove and then reinsert the battery to get it working. Slightly annoying, but really not that big a deal since I would use it for 12 hours a day, every day and it only happened 2-3 times per week. Until today, when it stopped working entirely, exactly 3 months after I received it. A green light was flashing on the top of it, which I believe is the low battery indicator, so I put a new battery in. The green light flashed again when I turned it on and it still wouldn't work. I tried 3 brand new batteries, just in case there might be a faulty battery, but to no avail. It just wouldn't work.
