what is this about?

I didn't use the device for long, but this unfortunately didn't grab me. But maybe I just didn't know how to use it roperly... lol. If someone combined the features of the sunu band with a smart watch like the dot watch, I'd be a lot more excited about it.

I was about to say a similar thing. Until they improve the hardware a bit, I don't think it really matters how nice the app is lol. It's like putting gold plate on a turd. Does it look nicer, maybe; when you look deeper though, it's just shit.

How are people supposed to read the Dot watch? The display is so small

Got me on that one. I eaven want to charge my sunu with some of my cell charger, but unfortunately they're damaged so I really don't even know.

I do have mine and I can say it helps.
When I am on my own, just with it and my cane, it sees the stuff that the cane can't see and I don't bump into signs and stuff as I used to.
One of the bands on it doesn't stay on it properly anymore, so I don't use it as much as I want to because the thing can fall off my hand and believe me, I don't wanna lose it like this.
The only things that are good on it are the sensor itself which is fine, the battery is ok and the vibrating time, but the rest is shit.
The touch pad is plastic and a very, very soft and ruberized one which scratches and can start peeling off from the sides if it feels like it, the micro usb port on the back is stupid, accepts just some cables and it can move, hold the sonar button and render it useless untill you manage to make the thing move back to it's position, don't know how that happens.
Also like I said, the bands are an ok-ish ruber, but with weak links, come on, I am sure there is more metal in the USB end of the cable than it is on this band.
It is one of the reasons I just stuck with mainstream tech in general and I don't have other blind products except mecanic ones like a cane or a brailler, I will probably stick with the ambutech cane I have and gps apps.
And probably a Samsung watch in the future.

Build quality problems are common in AT.  Maybe it's because manufacturers willing to take a risk on such a niche product with such a short run also tend to cut corners, or because the only way the AT company sees to pay the manufacturing fees is to skimp on materials and labor.
I don't think it can all realistically be chalked up to greed, but many companies like to claim that their products are durable regardless of the plain facts showing otherwise.

Oh god smart canes.  Please don't remind me of those stupid, breakable, unwieldy things...
Maybe some day, but not in this decade.

I used the WeWalk for a short period of time and was not impressed. I could be in a wide open space and the device always thought there was something in front of me. It kept vibrating almost all the time.
And as to how the Sunu helps, it tells you about overhead obstacles such as low hanging branches, glass doors, and some things the cane wouldn't pick up. Also, it can help you in lines. You can tell when you have to move up because the intensity of the vibration changes
