Packaging

Aside from the mouse, one finds a charging cable (USB Type-A to Type-C), wireless extender, wireless dongle, sensor ring skate, and quick start guide inside the box.

Weight

My scale shows around 58 g (+/- 1 g), which is exactly in line with the weight cited by Endgame Gear. The OP1we weighs 3 g less than the larger XM2we, only 2 g more than the similarly sized Pulsar X2 despite having a full bottom plate, virtually the same as the slightly smaller Cooler Master MM712, yet quite a bit more than both the G-Wolves Hati-S Plus ACE and 4K at 46 and 51 g, respectively, though these are smaller and do not have a full bottom plate. An excellent weight.

Cable

The OP1we comes with a paracord-like, braided charging cable (USB Type-A to Type-C). The connector is angled upwards, which is a design that was originally already announced for the XM2w, and has previously been seen on Zowie and VAXEE wired mice, and more recently on the LAMZU Atlantis and Atlantis Mini charging cables. In terms of flexibility, the cable is in the upper tier, and on par with the ASUS ROG or Glorious charging cables. Accordingly, playing while charging is possible without feeling overly restricted. The measured cable length is 1.80 m.

The charging cable also functions as an extension cable when used in conjunction with the wireless extender, which can be used to keep the distance between dongle and mouse as short as possible.

Feet

The feet on the OP1we are white-dyed pure PTFE (Teflon) feet. They are of above average thickness and have slightly rounded edges. Glide is excellent. A recession for a sensor ring is present, and the corresponding skate is included in the box, but must be installed manually if so desired. In addition, the feet recessions allow for larger feet, a set of which is available for separate purchase.

Kailh GO 60-65 gf Switch Set

For those not too enamored with the by default rather stiff Kailh GO main button switches, Endgame Gear offers a set of Kailh GO switches binned for an actuation force range of 60-65 gf, which is the lowest available, for separate purchase ($9.99). As the OP1we is designed with modding in mind, installing these new switches is conceivably easy: The two screws that need to be removed before the mouse innards can be accessed are readily exposed, and after doing so, all one has to do is unscrew the two switch PCBs, unplug them, plug in the new ones, and screw them in. The necessary PH000 screwdriver is included with the set, and the fact that it is magnetized deserves special mention. In addition, the screw posts have metal sockets, so even frequent screwing and unscrewing should be possible without any socket degradation. For a demonstration of the difference between the default and 60-65 gf switches in practice, please refer to the Button Sound Test under the Build Quality section. Keep in mind that how much of a difference this makes will depend on the actuation force of the default switches, which are subject to variance. On my sample, the difference is rather subtle, at least when installed in the mouse.
