This thing is great. I like to use Anki on my computer and during long sessions, it can get very annoying to constantly have my fingers on the 1 through 4 keys. This solves that issue perfectly. I can sit back is a comfy position and memorize what I need to memorize. This is exactly the quality I've come to expect from Stouchi.
The ring can adjust pretty well in size without getting too tight so don't worry if you have bigger fingers, it can probably accommodate them. Connecting was as easy as pairing any other bluetooth device and the latency was practically non existent. Battery life was also exceptional. Still on my first charge. If you use a lot of Anki this is a great accessory to have.
