Hello! I am Jyoti Sharma I stay at the AICB Hostel and i study in Miranda House College where I am pursuing my first year in B.A Hindi Continue. Yes! I loved wearing this jacket. when i wore it and you asked me to walk and turn as it vibrates, and really whenever it vibrated, i took a turn accordingly I thought something was in front, because of which i stepped aside. and as soon as vibration stopped, i moved forward So do you think this jacket needs some more changes? As far as I used it, I believe this jacket is doing a good job because, wherever there was an obstacle in front of me or my hand The jacket is vibrating accordingly to signal me, for which it has been made. I believe it is a good product. Thankyou Jyoti!
