I got this product for my cane. My wife said, "What are you? 12?" Hah, little did she know my plans of eventually turning my cane into a bluetooth phone.
Anyway, it's a great concept, but there are some design issues. Let's look at the good side first. The light only requires pushing the button on the butt end of the light. And the button glows in the dark. For a while. Until you're in the dark too long. Which pretty much makes it not any more handy than it sounds. And I'm not sure how waterproof it sounds. I'm not planning on swimming with it, but it does rain a lot here in the Pacific NW. Wow, and that's the good points. Oh, wait, a real good point is the fact that the light rotates 360 degrees. I hold my T-cane essentially backwards, so rotating the light, I can keep it in the right direction instead of turning the cane around if I want to use the light.
Now the bad. First is, to keep the cane from swinging too much out of balance, the clamp has to sit up high on the cane. Occasionally bumping it with my fingers, combined with the clamp being made to easily open, resulted in the entire assembly falling off of my cane numerous times. I ended up adding a real bolt in front of the finger clamp toggle.
Second is that the light is pretty fragile. As a previous reviewer noted, they had to tape it together. And if you open the light holder enough times, it won't stay shut, resulting in the light falling out of the holder. It's a nice enough light, but drop your cane a few times, and you definately end up taping the light together.
So I secured the clamp using another bolt. Then I replaced the fragile light with a durable aluminum 85-lumen light. Lumen is a measurement of brightness. If I had to guess, the original light probably is probably dribbling along at 15-25 lumens. Again, having the light holder open up on me with the original light a number of times, I also ran a black electrical wire strap around the light holder. I can still rotate the light, and I don't have to worry even if I do drop the cane. Or walking in the rain. The cane is about 5 oz. heavier with these modifications, but because the holder is high up on the cane, it only has a tiny effect on how the cane handles.
Bottom line, with modifications, what a great idea! If only I didn't have to make all those modifications.
Well...off to turn my cane into a bluetooth phone.
