I am severely visually impaired and as such my vision varies depending on the light conditions around me. When the light is in my favour, I cannot see anything below nose level for around 20 feet and my peripheral vision starts at around 10 feet. I also suffer with disability glare.
I came across the Sunu band review, by accident, on the Blind Life YouTube channel. I then looked at other reviews of the Sunu band before deciding to buy one.
The Sunu band is intended to be used in conjunction with a cane or guide dog, not as a replacement. The Sunu band detects and objects above waist level. It works by giving haptic feedback (vibrations) of varying intensity as you get closer to an object. It costs £288 including VAT, which you do not have to pay if you qualify for exemption in the UK, the cost then is £240. Prices correct at time of writing.
Although I’ve only had it a day it's already give me confidence when out walking when all my vision disappears, as it can detect objects I cannot see, walls, rails, low hanging branches etc.
One piece of advice, if you decide to get one is to make sure you learn how to use the different features. I found that by reducing the sensing angle in the sonar presets, I wasn't swamped with unnecessary feedback.
