Have also that Powerball... No idea where it is, to be honest since haven't been using it for a long long time. Yours come by default with the meter? I think it was an option when I bought it. The interesting thing and your post serve as a reminder for me to find my Powerball and start using it. With my increased typing activities at HIVE as of late, I may need it to get my fingers in shape again for more power typing {LOL}
Which of the 3 devices you showed is your favourite? Or did you mention this in the video and I missed it maybe...
I liked having the numbers on the Powerball to see if I was improving, but I'm not so bothered now. I quite like the spring gadget as I can just pick it up and exercise whilst watching a video or reading.
Did you ever get a medal for using these gadgets? 🏅well, now you got one, for the Powerball one 😉
I'm flattered
🙇
