If you're referring to GPS, it's very useful. We use them in conjunction with a cane or guide dog. Most blind people today use smartphone apps like BlindSquare and the Sendero/Aira apps instead of dedicated devices like the Trekker products.
If you're referring to smart canes, very few people use them because they're still quite new and don't offer many features that a standard cane doesn't, plus they're heavier.
If you're referring to object detection devices like the Miniguide or BuzzClip, they're very useful, but you'd still need to use them in conjunction with a cane or guide dog because they don't detect things like changes in elevation.

It also depends on what people are used to. Someone who lost their vision in life, and not used to using modern GPS, may find an audio GPS system very confusing.
I find most people can usually figure out how to use a navigation system, if they are motivated to learn it and willing to make mistakes in the process.
