In terms of quality the build quality of this trackball is very good. The track ball moves smoothly and once you set up the DPi on the mouse and the mouse settings on your PC/Mac its fairly precise. The buttons are what I would describe as silent tactile buttons. They make a muted click noise and there is good feedback when you push them. Really good. It operates pretty much like the 2.4G wireless version of the Bitra. The main difference is that it connects via Bluetooth. For my desktop PC the dongle version pretty good as the trackball stays with it, but for my MacBook the Bluetooth is far more convenient given the MacBooks lack of USB-A ports. Getting it connected to the MacBook was pain free and easy and its really easy to take the mouse with eth MacBook when I move around the house etc. My nit pick is that the power button underneath the mouse is a bit small and not so easy to turn on and off.
I also have the Deft Pro trackball and if you are wondering the Deft Pro more ergonomic in the hand by a fair margin although in my view feels cheaper and not as well built. Some of the buttons on it are also of the "clicky" variety. The battery life on The Bitra Bluetooth and also the Bitra dongle version also seem to be far better that the Deft Pro.
In an ideal world if Elecom would make a slightly bigger Bitra (same build quality and buttons, not as big as the Deft Pro) with both Bluetooth/Wireless Dongle and USB-C connection and powered via 1 or 2 AA batteries than I think this would be the perfect portable trackball mouse.
