The Attack Shark R5 Ultra, essentially a re-label of the IPI Float with some changes is a delightfully solid mouse.Some quick notes:• Comes in at 43 grams with two strips of grip tape applied• Carbon Composite frame is very rigid and feels higher end• Main clicks are Omron D2FC-F-7N 100m, not the Optical D2FP-FN2 switches as is shown in some media• Great shape on the thumb buttons that protrude just right• Slightly above average skates, with included replacements• Large external dongle, more for looks over functionality• Decent battery life, at least on lower polling rates• Works good with claw grip though a little on the narrow side• Slightly flat for palm grip, though your taste may vary• Included cables are not great, both the braided and the coiled. Too stiff.• Web driver is simple and straightforward with a handful of adjustments• DPI button is on the bottomThe longer part for those who want the details:This mouse upon placing it in the hand feels almost like air, its balanced well and is a fairly universal shape that many people can work with though personally I would have preferred it to be slightly wider in the mid section with my fingertip grip. The Carbon Composite plastic used here is extremely rigid and feels higher grade than the average mouse material. Looking close at it or even digging into it with a nail it feels harder and more substantial. Despite being mostly holes, there is almost no flex whatsoever. It is however rather slick and lacks grip, though there is a set of grip tape provided with this specific set which definitely improved my comfort on the sides. With two strips applied it hit 43g on the scale, which puts it solidly in a great zone for lightweight mice.Main clicks are not the Optical switches shown in the media and some promo, nor are they Kailh, but Omron 100m switches. Attack Shark issued a statement that the switch selection was changed somewhere along the line for "key sound performance," however the media was not updated properly to reflect the change. They are satisfying enough though and I can't find much of any fault with the performance, but are nothing exceptional to note. I hope they hold up just as well over longer periods. Fingertip placement affects the feel of the switch slightly, with a higher up grip being more firm with less travel, and lower down having a slightly looser feel. Not bad, but nothing exceptional to note. Scroll wheel feels fairly standard, on the lighter side but still has enough notch to the encoder to prevent accidental input.The thumb buttons have a very pronounced shape with an outward crease along the center line that catches the thumb in just the right way without being too chunky. They don't sink in too far when pressed either, and this shape has become my favorite out of the half dozen gaming mice I have on standby.The 3950 sensor works just as it should with excellent tracking, no spin out and has some extra features. In the driver polling can be adjusted from 125 to 8K, LOD has three heights, Motion Sync, Ripple Control, and Angle Snap are all supported. Using a corded connection drops the polling to 1K max, and then when on Bluetooth mode the driver does not connect and reports back only at a basic polling rate. Running the polling tester my PC could pick up roughly 6800-7000 Hz from the wireless connection, so 8K is possible, it will also depend on system load and other factors of course. Higher polling has more effect on battery life and has diminishing returns so I run it at 2k personally. Said battery life despite the tiny size of the cell is acceptably good, and I charge it roughly once a week.The included skates are all right but nothing exceptional, users of customized mice or ultra high end will find them a little more draggy, but they are serviceable. There is an included set of extra skates that are white which I have not tried yet, they could be slightly better if they are the higher grade PTFE.One of my biggest disappointments with the mouse however is in the cables, both of them. This kit comes with an additional coiled cable with an aircraft style connector as is more commonly seen on keyboards, though its an odd design. The coil is placed far back as to allow for a long enough tail to use on the mouse wired, but that places the coil essentially back where you will never see it and the wire is too stiff to use for mousing IMO so I don't think it is worth the premium vs this mouse that is sold without it. The regular black braided cable that is also included is also far too stiff, and I ended up replacing it for the time I used this plugged in with one more flexible. The dongle is chunky, and is an external type meant to be placed on your desk close to the mouse connected with one of the Type C cables It has a status LED but there's not much of anything to note about it. The mouse itself has its own status LED inside the frame, but its turned off most of the time unless under low battery, pairing or wired.All in all...
