If you’re familiar with the Logitech G203 mouse, then you might get déjà vu when you see the G305.

Logitech released the G305 Lightspeed mouse as a wireless variant of the G203. Both mice are targeted at a similar audience and have a similar physical footprint too.

If you’re not familiar with the G203, I still got you covered. Logitech sent me a review unit, so I had a bit of time to play around with the product.

As usual, I’ve put all my thoughts together in one piece, so you have a good idea of what my opinion is in terms of the build, functionality, and the value for money that Logitech offers with this model.

Based on my experience with the solid performance of the Logitech G203 wired mouse, my expectation was that results with the G305 would be similar. Was it a short-sighted opinion? Let’s find out in my Logitech G305 Lightspeed review!


As the name already implies, Logitech is using its lightspeed technology here for excellent wireless connection. It’s been pretty good with other models from the manufacturer, so I fully expect the same standard here.

The key specs of the mouse itself are as follows:

Size (mm)WeightPolling RateSensorDPIUSB Type
116.6 × 62.15 × 38.299 grams1000hzLogitech HeroUp to 12000USB-A

The Hero sensor is one of the best you’ll get from anywhere, so it’s great to see on a mouse at this price point.

However, while it may include “lightspeed” tech, there’s nothing “light” about the weight of the G305.

At 99 grams, it is at least a full 36 grams heavier than the popular lightweight alternative from the same manufacturer – the Logitech G Pro X Superlight wireless mouse. It’s a relatively small mouse, but it’s thicc.


Build Quality

When you’re purchasing a product from a reliable manufacturer like Logitech, the last thing you’d expect to worry about is build quality.

Thankfully, the build here is great overall and the mouse feels solid. It is made of plastic, but the plastic feels solid and does not creak or wobble in any area.

The palm rest panel does feel more flexible than the rest of the outer surface, but that is understandable as it is removable.


When it comes to gaming mice, I think we can all agree that size matters.

Now, I already mentioned that this is a small one, but I really think the shape and overall design make it a tad difficult for people that use the palm grip like me.

It’s a situation-specific issue, so I’m not going to take major points off because of it. In fact, if you don’t use the palm grip, then it’s pretty much irrelevant to you.

On the flip side, the “egg” shaped body of the mouse makes it suitable for both left and right-handed users. It’s a nice change of pace from the flood of right-handed mice on the market.


There’s a nice matte finish to the coating here that feels smooth to touch.

I also had the Razer Orochi V2 while making this review, and that mouse felt coarse in comparison. The G305 is also almost shiny when reflecting light, whereas the Razer did not reflect much.


Underneath the mouse, you get 6 PTFE feet nicely spread out. They’re not the largest, but considering the overall size of the mouse, they’re fine. There’s also a small pad at the bottom that should prevent scraping when you’re dragging the mouse about.

Buttons and Switches

There are 6 programmable buttons on this mouse – the left and right-click buttons, the scroll wheel, a CPI adjuster south of the scroll wheel, and two side buttons.

I mentioned earlier while talking about the shape of the mouse that it is suitable for right and left-handed users. While that remains true, I should also mention that the placement of the side buttons is more suitable for right-handed users than lefties.

The switches on the mouse 1 and 2 buttons are reliable and have no pre or post-travel, which is nice. The side buttons are smaller than others, but they should be easy enough to reach for most people with a bit of grip adjustment.

The middle mouse click on the scroll wheel is crisp and clean, and the wheel itself is pretty smooth and consistent.

There’s also a dedicated button for swapping between the DPI values that go from 400, 800 to 1,600 and 3,200.


If you were wondering where all the weight came from, it’s the battery. Those 99 grams take into account the size of the AA battery that you need to power the mouse, and it makes the overall package significantly heftier than it would be without the battery.

Now, this is a situation where you have to give something to get something. If the weight of the mouse is a potential dealbreaker for you, then you could just swap out the factory-included battery for one that weighs less.

I tried that with the Razer’s battery and the weight of the G305 fell to 88 grams. However, if the battery life of the included AA battery is as good as advertised, you will be sacrificing a significant amount of battery life for reduced weight.

The regular battery is expected to last up to 250 hours of consistent use, which is very nice. It’s an alkaline battery and that contributes to its hefty size, so you could get a lithium replacement that would last for even longer and still reduce the weight of the mouse.

Alternatively, you could also put the regular G305 battery into endurance mode, which would make it last for months. However, as good as that sounds on paper, it appears that endurance mode brings down the polling rate to a maximum of 125hz, which is pretty low for a gamer.

The inclusion of a battery might seem a little old-fashioned, but it also means that you never have to plug anything into the mouse. If you’re on the move often, that can be a convenient compromise.


The RRP of the Logitech G305 Lightspeed is $59.99, which is the price you’ll typically find it listed for on the official Logitech store unless it’s on sale.

It’s often available for less than this on Amazon.


Logitech’s G Hub is the software that comes with this package. It’s a pretty basic tool that lets you adjust DPI (if you can’t or don’t want to use the physical button) and switch to the aforementioned “endurance mode”.

You can also do button assignments, but I left that page well alone because I’d probably mess something up if I tried.


If you’re looking for the best gaming mouse, then look further because performance-wise, this is a good mouse, not a “great” one.

Points in its favor include a solid build, nice coating, removable back, and the quality assurance of purchasing a Logitech product. Oh, and it’s a good price too.

Apart from the grip issue, the weight of the mouse is also something to consider. Nearly 100 grams is a lot for a small mouse, but at least you have options.

If it’s the only thing stopping you from buying this, then get a lithium battery to reduce the weight. With that out of the way, it’s easier to enjoy the fantastic Logitech sensor and other tech built into the mouse.

Logitech G503 Lightspeed

The Logitech G305 Lightspeed is a good gaming mouse at a good price, but is not great in either regard.
