CHERRY XTRFY M64 Pro

[pzogel]

Newly-formed CHERRY XTRFY present the right-handed ergonomic M64 Pro, weighing no more than 54 g despite having a solid shell. Equipped with PixArt's PAW3395 sensor, the M64 Pro musters up to 90 hours of battery life, and even delivers true 8000 Hz wireless polling.

I would disagree about this mouse being pricey considering how a lot of other 8k (or even 4k) mice charge extra for an upgraded dongle. They might be confident in pricing because of their unique shape?

 

[Onasi]

The shape is… interesting. Not for me, though, I don’t think this is particularly suited to fingertip.
Impressive how wireless is ever so slightly faster in click latency. I mean, you wouldn’t notice, hell, anything below a certain threshold (say, 4ms if we go by pzogels table) is a wash, but still.

if only it had a decent battery capacity, like 60g is already really light idk why they are pushing it to 54g

Yeah, and those mice usually cost about 90-100 bucks without the 4K/8K dongle.

They are confident because of the generally good hardware, build quality and PnP in the last few years.

Tbh, they could push it much lower. I mean 54 grams is decent, but eh.

If "pricey" is a con, "But Expensive" should be a must.

Presuming they could, should they? Lighter !== better; that is to say mass is a preference as much as anything else. I personally don't like mice that are too light.

Connection reliability with a couple of 4K mice is something I've struggled with. Do we really need 8K polling?

At 2000Hz polling, we're talking an average of 250μs delay from mouse-polling. When the click-to-pixel chain is still ~30ms even on a high-refresh setup with all the latency-reduction technologies enabled, does shaving more off the 250μs mouse latency really achieve anything other than high cost, reduced battery life, and connection stability issues that simply never arose at 1000Hz, even at longer distances like sofa-to-TV rather than deskt-to-desktop.

Yeah, it's preference, some people are better with a bit heavier stuff, but on the other hand, lighter IS better objectively, just based on physics alone (less force needed to move, less inertia, which leads to quicker direction changes and less fatigue over longer periods of time). So they absolutely should, there are plenty of other manufacturers on the scene who won't do that (in the foreseeable future, at least).

0 grams would the ideal for me, but that's obviously a stretch. Getting back to reality, I would be more than fine with something between 15-20 grams.

Well, these kinds of polling rates are not for sofa-to-TV, but this is a given. With a 360 or more so a 540 Hz display, the smoother cursor movement and the slightly better responsivity are noticeable, if you have consistently very high (multiple hundreds) frame rate and the game supports sub-frame input (and you are physiologically able to notice the difference, because not everybody can). This is for high-skill eSport, played with state of the art hardware.

Yeah, at the very bleeding edge of extremely high skill eSport players, perhaps I can see where you're coming from - but I would imagine they all have sponsorship from Razer, Logitech etc and have to use their mice.

The other thing, is that if there's even a tiny chance the 8K polling poses a risk of dropping out in a tournament, they'd not touch it with a 10-foot pole. Reliability > performance when it comes to mission-critical pro-level gear.

That might be true for CS, but necessarily for other titles.

Some of my friends have encountered disconnection issues, I don't know if this is an isolated case or not?
