I myself have tried nearly every Logitech mouse there is since early 2000 as well as numerous top gaming mice from other brands since then and I can wholeheartedly say that there is no mouse currently that can compete with the g303 in terms of just shape, click-feel, mouse-feet or bottom of the mouse, aesthetics in terms of how the mouse looks but also just the amazing honeycomb light pattern on the sides, and just overall design. Out of all of the mice I have tried in my life, the g303 is one of the best fitting and comfortable mice that I have ever used, period. when I grip this mouse, it just feels like a glove for my hand and I have medium-sized hands. When you grip this mouse, it kind of leaves your hand in 1 position, which is good because it improves accuracy and doesn't make your fingers or your hand slip off of the mouse. The keys on this mouse are soo good as they are very easily clickable, but not too sensitive either. I love the RGB honeycomb pattern on the sides, which I have set to slow cycling effect. I love it's simplistic design as I do not like too many unnecessary buttons and even left-handed people love this mouse as well as it is almost ambidextrous. I love how light the mouse is and the fact that it is not too tall so my hand always feels comfortable and doesn't get tired from long hours of usage. The sensor on this mouse is so responsive and accurate that it literally feels like I have an extra hand. Also, the software that Logitech provides for free with this mouse allows you to auto-tune your surface to the mouse, whether it be a hard or soft surface, which makes your mouse even slightly more accurate. I also love the smooth scroll wheel. Lastly, the 6 pads on the bottom of the mouse bottom surface are very nice as well since they provide good balance and it feels like butter when you slide this mouse across your mouse pad. None of the current Logitech mice have mouse feet on the bottom of their mice that are as good as the g303 mouse feet in my opinion. I mean seriously, I tried the g pro wireless recently and I really tried liking it. I tried using it for 2 months straight and just went straight back to the g303, because the g303 is just better. The new Logitech mice like the g pro wireless are too long, too tall for the hand, awful bland design and shape, awful mouse feet, it's like they went backwards in terms of quality after someone at Logitech decided to discontinue the g303 simply because of few quarters of bad sales and initial negative feedback even though people are still buying the g303 to this day for 10 times higher from third-party sellers because it's discontinued. Some might say they hate the shape, but I love it personally and have seen tons of reviews on youtube and online in general where people praise the shape, especially people who have smaller to medium-sized hands. All of the current mice that Logitech has seem to be designed for larger hands in general and not many mice at all available from Logitech for smaller to medium-sized users. Also, some might say that this mouse is only popular due to some streamers using it exclusively, but I don't think this is the case either. I myself was not aware that some other people got this mouse only due to some streamers using it because I myself tried the g303 when it first came out to see if it was any good and I immediately loved everything about this mouse and still do. It almost feels as if Logitech designed the perfect mouse in terms of shape, comfort, perfect bottom mouse feet, perfect aesthetics in terms of the honeycomb rgb pattern on the sides, perfect design overall and then decided they should discontinue the g303 by only judging a couple of quarters of bad sales or initial negative feedback/response. However, years went by and after people still buying the mouse discontinued, people realized it actually really is a good mouse. Other than this, I can't understand why Logitech even discontinued this mouse in the first place unless it was an issue of mass-producing it due to its high quality, but this doesn't make much sense to me either as there are more complex mice they have made that are still in production. Literally, the only thing I can even think of that is bad with this mouse is the reported rattle issues on it, which was actually fixed by Logitech a year after it's release. Also, the double click issue that happens on the mice after a few years of usage which can just be fixed by replacing the mouse switches anyway. Anyway, it really is a shame that the g303 was discontinued because I can honestly say that this mouse is one of the best products that Logitech has ever put out and I really hope to see its returns one day. The g303 needs to come back as either a re-release for a wireless version with a better modern sensor but same design and shape OR at the least a re-stock. Those are my thoughts, I know some might disagree, but yes, there is still a large cult following for this mouse due to how amazing it is, just check the Logitech G or MouseReview Reddit or online in general and you will see there is still a huge demand for this mouse and it's for a good reason because it's an amazing mouse and needs to be released as wireless one day or at the least re-stocked
