Je l'utilise dans ma voiture. Il me permet d'avoir une bonne posture quand je conduis ou quand je suis passager. Je n'ai plus mal au dos et aux jambes après de longs trajets.
The fans arrived in past month, came without adaptors, and just purchased those. I have used one of them so far and found it turns itself off after a small period of time.
It’s very comfortable and my back is much better. I work an eight hour day driving it helps my legs so they don’t go to sleep and my ankles for not swelling.
I purchased this watch primarily for the blood sugar monitor so when I showed it to my doctor he said it doesn’t work effectively and do not use it for blood sugar monitoring. So it is now in the trash. Careful what you buy online.
