4.0 out of 5 stars Nice mouse, but not perfect.
By Mergatroid on November 15, 2018
Logitech G903 Mouse

I really purchased this mouse because I love the idea of having a wireless mouse you don't have to charge. Needless to say, I'm going to pick up the Powerplay mouse pad as soon as I locate one reasonably priced.
I have talked to Logitech about this, and they say the reason retail stores are not carrying it in Canada is because there is a Canadian government regulation preventing them from selling it. That would explain why prices are so high on Amazon.

As for the mouse, it seems pretty good so far. Over the last 15 years I have been using quite a few wireless mice, from cheap laptop type mice to expensive gaming mice. I don't see anything too special about the G903. I also have a RAT 9, and a Steelseries Sensei wireless mouse on my desk right now, and they both work as well as this mouse.

I have found that the G903 is slippery if you use it after washing your hands well as there is no real grip on the sides other than a few lines etched into the plastic. If feels very hollow/plasticy. The Steelseries Sensei actually feels much more solid (I won't compare it to the RAT 9, which is a very heavy mouse for people who like heavy mice).

The buttons feel great, and have a nice quality feel to their clicking. The DPI is easy to change with two handy buttons, and three LEDs that give you an idea how the DPI sensor is set. Those LEDs and the one under the palm can have their colours changed, have different effects or just be shut off to save some battery time.

This is an ambidextrous mouse. Personally, I don't like that in a mouse (the Sensei is the same way). For the price, we could have had two more handy buttons on the right side, but instead we get duplicates of the two thumb buttons for lefties. I would prefer to have two more buttons. On the G903 Logitech makes covers that cover the buttons you're not using. This is a very high priced mouse, and adding an expense like this puts me off a little.

The mouse wheel is pretty nice. I used to own a Logitech MX Revolution back in the day, and it had this awesome mouse wheel (the best one ever made). If you moved the wheel slowly, it would click. If you moved it quickly (like "flicking it") it would spin freely. This was super handy and worked very well. Years later, they made a few mice similarly, but you would have to press a button on the bottom of the mouse to change from clicky mode to free spin mode. The g903 works the same way, except they have at least put the button on the top of the mouse instead of the bottom. It's too bad they didn't use that old MX Revolution wheel design. I'd rather pay for that than two lefty buttons I will never use. Note that you can also tilt the mouse wheel, a classic Logitech wheel feature, for scrolling side to side. It will take me a while to get used to this again since I haven't used a Logitech mouse since the Revolution.

You may notice the Powerplay mouse pad is very expensive here on Amazon. I spoke to Logitech about this via an email, asking why their site would not sell it to a Canadian address. They responded that there is some Canadian government regulation preventing them from selling it in Canada. I find that odd considering you can purchase wireless phone chargers, and you can purchase the Corsair MM1000 QI Wireless charging mouse pad in Canadian stores. Too bad that pad wouldn't work with the G903.

The software is pretty good, though a bit unintuitive at first glance. You can turn all the LEDs off to save power, or you can change the colours or effect. People familiar with gaming mice will ave a good idea what else to expect. There are profiles, colour control, dpi control, button mapping, surface tuning, battery information and other settings. The software apparently controls quite a few different Logitech products as it has bugged me about the Powerplay (again, ironic considering you can't purchase it in Canada other than online), and there is a section for one of their keyboards. You can also save profiles to the mouse itself as it has some memory.

Overall, it's a pretty good mouse. To be honest I'm having a hard time figuring out why it's so expensive. It doesn't come with any of the wireless charging mechanism (all that stuff comes with the Powerplay mouse pad), and there is no charging dock (you have to plug the cable in to charge it, which is pretty ironic considering you are paying so much for a wireless mouse). I know other mice, such as some Razer mice, use this same method. It seems odd to me that these companies think people want to pay so much for a mouse that's only wireless some of the time. Other mice I have owned, such as the MX Revolution, and the Steelseries Sensei have batteries that last longer, so as long as you put the mouse in the dock whenever you're not using it, it will always be charged. Even of you forgot for a day or two, it would still be OK to use, and you would just place it in dock when you were done with it.

The G903 software tells me there is about 33 hours on a charge (with the LEDs off), or about 23 hours with the LEDs on. I wonder if this is a limitation of the battery, or the sensor and wireless technology? It seems odd that a very well made, 15+ year old laser mouse like the Logitech MX Revolution can have four-five days of power available before needing a charge, while this mouse will barely last a day. This isn't a big problem, and is fairly common in modern wireless gaming mice. However, without the Powerplay pad to keep it charged all the time, you will end up either having to plug the cable in when you're done using your computer, or having to plug it in while using it, thus losing the benefit of having a wireless mouse until it's charged. I find a dock to be a much better solution.

I got this G903 on sale here at Amazon for $139. If I added the mouse pad via Amazon it would cost me another $200. I don't see how any company can justify their wireless mouse pad selling for a price like that, although it's not all Logitech's fault. However, this pad goes for a hundred bucks in the U.S., so it would likely cost $130 or more if it was available locally. Considering the Corsair QI Wireless charging mouse pad does something very similar, I fail to see why the Powerplay pad is so expensive.

If you have the money to blow, you really want a wireless mouse, you like the Logitech brand and Logitech quality, then I can recommend this mouse as it seems to have all of that. If you're just looking casually for a nice wireless gaming mouse, there are less expensive alternatives that are just as good (like the Logitech G703).
The only benefit to this mouse over the G703 that I can see is the G903 has a few more buttons, like the two DPI buttons, and is ambidextrous with the two added (hidden) thumb buttons on the right side. In fact, the G703 has rubber pads on each side to keep it from feeling slippery, and yet on the much more expensive G903 they have been left out. Go figure.
