Item arrived on time and in good condition.
I needed a wireless mouse for my new GMKTec Mini PC which I will review after I've installed linux on it. Right now I'm testing on my big old MSI windoze lappy in the pic.
This X2 fits my large/long hands well and I like it. The front is low enough for the buttons to be comfortable (they're not horizontal-ish like on some mice), and the Forward/Back buttons are positioned high enough that I have thumb room and almost never hit them by mistake. It's super light too, at least partly due to no AA battery; it charges on USB, like everything these days. Tracks well on the surfaces I've tried: white desktop, brown mini-bookcase top, even a business envelope with a window - and of course on mousepad.
It comes with a nice 6' USB/micro Type-C cable, a USB 2.4G receiver (stored in a tiny compartment on underside of the mouse), and sticky stickers you want to stick on right the first time, or you might be stuck with where you stuck them.
It connects via 3 different ways using a 3-position Connection Mode selector underneath with questionable position names:
• Bluetooth ("BT") - This is flaky even for Bluetooth. I have nothing but trouble with it. You need to press Connect button underneath, and I needed to navigate via keyboard (tab, shift-tab, arrows, space, cr) while BT was being paired. Then the mouse stopped dead in about :30. I reconnected and about :30 later it stopped again. I rebooted the lappy, removed the device from Settings to start from square 1 again, but now (without using the keyboard) I can't connect at all: the X2 doesn't show in the list. It's totally losing a star for this.
• USB cable ("Off") - This worked as expected right away and reliably.
• 2.4G Receiver ("RF") - This worked as expected right away and reliably and is the mode I use. But as said, the 2.4G receiver is stored in a tiny compartment on the underside of the mouse. I was starting to panic until I found it.
It loses a star for the ultra-flaky Bluetooth. It also loses a star for being twice the price of other 2.4G/Bluetooth mice. But since it fits my long hand so well, I still recommend it, at least for people with long/large hands.
