Hi @Lefty1,
I’m afraid I don’t have this product but it definitely looks interesting! There’s only a few reviews which I’m sure you’ve looked through already. Has your OH already got regular Kegel balls? If she has then there are lots of free apps you can get that do the exercises and tell you when to pulse, squeeze, relax etc - it obviously wouldn’t record when you squeeze etc but you can log your progress and may be worth a go if you’re hesitant about spending the money.
Brenna also points out in this post below that there’s the Sexual Happiness Promise so if it doesn’t work for you then there’s always this - I haven’t personally ever needed to use it but it’s good to know is there
