Since my trusty GigaByte Aivia M8600 finally gave out completely I had to get a new mouse. Got me a Logitech Gaming G903 I choose this because I had a few prerequisites. It had to be wireless, I hate it when the cable works against me. And it had to have on the fly dpi adjustment. Apart from that all bets were off. At work I've been using a Performance MX for many years and it's a very high quality mouse, that served me well, so I choose Logitech this time. The GigaByte was more of an impulse purchase for me, but it turned out pretty good. But it slowly deteriorated. It came with two replaceable batteries which was great because I could continue playing when one drained. Unfortunately one of the batteries died soon after the warranty period ended. And it wasn't as much fun with a single battery. But then it got worse, as the mouse decided to not work wireless at all about 6 months ago. So I've been using it wired since. It came down to a head to head between the G903 and the G PRO, and the deciding factor in the end was size. I don't know why logitech makes such small mice, the G903 is by far their largest but even this is thinner than what I'd like, at least it's long enough, because that was the real problem, I absolutely loath mice that don't fill my palm. It feels like I'm pinching something tiny. So after much ado about nothing it's time to start the actual first impressions: It comes in an expensive looking box, which I'm not a fan of, they could've probably shaved 10% off the absurd price by putting it in a regular plain box. They also made sure that the fancy box cannot be re-purposed for anything useful because it opens almost at the bottom. Waste of money that is. The mouse itself feels like it's made out of the cheapest plastic possible. Probably to save weight, but still at this price point I expected something rugged like the MX, not a flimsy piece of cheap plastic. And it is light, very light indeed. So far I'm not sure if that's a pro or a con. But they did include a weight plate I can install if it is too light. So that's definitely a pro. It only comes with a single cable, again at this price they could've included two separate cables one for charging and one for the wireless transmitter. So you don't have to unplug the transmitter if you want to charge. The aivia not just came with two batteries, it came with a carry bag, docking charger, and two sets of cables, and it cost less than this. Since I'm cheap I didn't order a powerplay mat for it, maybe later if the charging becomes an annoyance. But then again I use my mouse in a very small space I doubt their large mat would fit. Of course the real test will be gaming, but the control and response already feels great. I also "calibrated" my desk surface, IDK if it's snake oil, or actually matters. The mouse wheel also feels flimsy again probably due weight saving. And the locked mode feels a bit tight to my taste, I hope the resistance will become lighter after some usage. Free wheel mode is useful for productivity on the other hand so glad to have that. So to summarize: It feels cheap, but works great. It's definitely not great value for the money if you buy it at MSRP. Thankfully I got it much cheaper. Logitech wants $200 for it, I paid $130. (Yes the US page lists it for $150 but I'm in the EU, we always pay a premium on cars and electronics) I'll check back after breaking it in, possibly.
