Logitech G303 Daedalus Apex Introduction

Logitech has been making mice for about as far back as most PC users can recall, enhancing and refining the input peripheral over the years. Their new G303 Daedalus Apex is an advanced lightweight gaming mouse that builds off the foundation of previous offerings, and it’s launching today.

Getting straight into the details, the core design is very similar to the existing G302 Daedalus Prime MOBA mouse, but with an upgraded sensor. The G303 uses the same optical sensor found in Logitech’s G502 Proteus Core, the PMW3366, which is regarded as one of the most advanced sensors around. With the G303, Logitech has elected to reveal some additional details about the sensor, which are included in the following table.

We won’t cover all of the features, but the sensor is definitely one of the most advanced options around. This is currently Logitech’s best mouse sensor, and the Delta Zero along with Zero Filtering/Smoothing are features that gamers in particular can appreciate, as they ensure there’s no acceleration and no additional lag generated by smoothing input over multiple samples. (Note that it’s necessary to also disable the OS smoothing/filtering aspects to get the unadulterated experience.) The resolution range of 200-12000 DPI is quite large, and personal preference certainly plays a role in what DPI an individual user likes; the G303 allows switching between up to five settings on-the-fly via the Logitech Gaming Software.

Logitech has also refined the buttons with metal spring tensioning on the left and right buttons that’s designed to improve the responsiveness, feel, and durability of the buttons. Rated at 20 million clicks, that’s equivalent to someone clicking the buttons every second for twelve hours a day, seven days a week for a full year. Or for those who prefer not to suffer from RSI, you could use the mouse and click the buttons on average 10 times per minute for eight hours a day and you still wouldn’t hit 20 million clicks even after ten years – at which time you’d likely be using a newer mouse regardless.

Besides the sensor and button specifications, which are obviously important for the target market, Logitech also has customizable RGB lighting on the mouse and a high quality braided cable. The weight of the mouse is very light, and the body is relatively small compared to some gaming mice. The total of six buttons (left, right, two thumb buttons, the scroll wheel, and the button behind the scroll wheel that’s typically used for DPI switching) is a bit limited compared to other offerings, but the Logitech Gaming Software does offer a full range of customizations and macro features.

We could go on but the key takeaways are that Logitech has attempted to create the best possible sensor with an extremely precise tracking system and a high quality and comfortable chassis. This is definitely a niche product as many users are more than happy with less expensive mice, but for competitive gamers that live and die by their mousing skills, Logitech hopes to win them over with the G303.

    ironic? support might suck because nobody ever uses it... they make the most durable products, far better than razor... that's coming from a computer programmer that is still using the same keyboard from 5 years ago and have easily passed a million keystrokes

    AND, I did actually have to use their support last month for first time in 20 years of computing, and they replaced my defective keyboard by just sending me a new one... and it was their backlit $80 keyboard... all I had to do was email them a picture of the broken keyboard and receipt of purchase... I didn't have to ship old keyboard back!

    So are you just a spammer on the payroll of another company? You are posting the same exact post and link with the same username on lots of tech sites.

    Love the style of this. It looks like a very decent successor to my old G500.

    It does look nice to replace a g500 (have one myself) with the exception of not being able to adjust its weight.

    I really want to get another Logitech mouse. But I can't. Two factors or reasons:

    1) I already have a Razer mouse that's fairly new
    2) Logitech's software package is overly bloated

    Obviously I am not in the market for a new mouse. Even if I was, it's hard for me to look at Logitech now. Logitech's mouse software is just too big and it often interferes with other software. So if you got useful software to help you do things like hardware monitoring, overlay systems, video capturing or broadcasting, somewhere within that mix, Logitech's mouse software will not work for you.

    Logitech has completely redesigned the software suite for their new high end mice like the G502 and this mouse with the new sensors. The software is completely different and greatly reduced from their usual mouse software. They have new software for their new mechanical keyboard too. I'm a fussy mouse guy, have tried most of the high end mice, the G502 is the best and most consistent mouse I have used. It has eliminated weird acceleration issues and inconsistency that I found with other mice.

    yeah i have bought logitech for gf and my laptop even though i loved my ergo sets gfrom ms, and had gyro mice and others. all get lots of use years of use no problem with any logi. i sprung for that 502 on sale this this is awesome for me i love unlock scroll with weight spin that sucker or the indicators on side showing each custom dpi profile multi on fly and paddle switch for in game frag the button assign surface cal etc all so easy and work. the razor i just got what garbage at 3 time price and sneaky software that feels like dataminer. probably a real gamer can go crazy with all the buttons (but not too many) and custom on this the wire sheath etc all top class.

    * complains about bloated mouse software
    * has a Razer
    * is keitaro

    The G-software they've been using for the last little while is really light and the settings actually save to the mouse firmware so you don't even need to run the software all the time.

    P.S. Razer Synapse is awful, I don't want to be forced to sign up for and then log into an account just to configure my keyboard/mouse. I have a razer BlackWidow and I now get constantly bombarded with the Razer Synapse setup wizard I refuse to install every time Windows seems to decide that I need a driver update. That's right, you don't even need to download the bloatware anymore they're distributing it via Windows Update. Why does a keyboard need a massive bloated control panel anyway?

    Yeah, the software certainly isn't what it use to be - and the product designs and direction logitech is going is disappointing for me. I use to be a huge fan of their offerings, but I've found more and more their products are not as great as they use to be. I was completely disappointed in the mouse-click tolerances for their MX/VX lines, and their discontinuation of their high-end speaker lines (or dilution, however you want to spin that; z-5500 series to be exact).

    My one question for this mouse that wasn't answered was, does this work on glass, frosted and transparent? Does fluorescent lighting on said glass interfere with the sensor (reflected or nearby)?
