The throbbing at night was so bad I'd hang my foot off the edge of the bed just to sleep. I wear this 15 minutes before bed and by week 2 the joint wasn't screaming anymore, I even got my regular shoes back on without wincing!

I'd basically accepted that bunions had ended my running. I wore this 15 minutes a night and by 3 weeks in the sharp pain at my toe joint eased off, I got through a long run without changing my stride. I'm not hiding my feet anymore either.

I live it ! It is really effective!
I'm a runner and I'd honestly started to think bunions had ended that for me. Sharp pain at the base of my big toe every time I pushed off, and it was changing the way I ran. I was skeptical about the EMS part but you can feel the muscle working when it's on. A few weeks in and my last long walk didn't leave me limping. Not a miracle, but it's the first thing that's actually done something.
I've bought every silicone spacer and night splint on Amazon and they all did the same thing: felt fine while I wore them, toe went right back the second they came off. This is the first one that's different because it's actually working the muscle, not just holding the toe. By the end of the day my foot used to be red and swollen and now the swelling is way down. I'm back in my normal shoes.
The throbbing at night was the worst part. My big toe joint had its own heartbeat by 1am and I'd end up hanging my foot off the side of the bed just to fall asleep. I've been doing 15 minutes with Kadvio before bed for about three weeks now and the joint isn't screaming anymore. I actually slept through the night twice this week, which hasn't happened in months. Wish I'd found this before I started looking into surgery.
I'll be honest, I almost gave up in the first few days because I expected it to fix everything overnight. It doesn't work like that. But once I stuck with the 15 minutes every day, the pressure on the joint really did ease up and the ache I get from standing at work all day is much more manageable. You have to be consistent, but it's worth it.
Doesn't fit right at all

Reviews are repeated. Fake or scam????
No instructions provided on how to use the device. Only a generic statement - describing otter devices but not the one ordered.
This thing really works. I get migraine headaches multiple times a week. When I ordered this product, I didn’t expect much. To my surprise, it didn’t just prevent headaches, it actually reversed one that was already in progress.
It feels great! I had no discomfort at all. I don't know if it is a permanent fix, but I can tell you the relief is real. Even if I have to use it every day, it is worth it. I have only used it for two days, but I am not disappointed.
Very nice product. Had to place a pad under it because it was too low to the ground.
It's been a few weeks and so far this seems to be preventing the headaches I get at the base of my skull.
