This type of material should be tested at night.See the pictures. These are black stickers that reflect as a light grey/white color when hit with a flashlight at night.These are good additions to any night rider's equipment. The customer service is also very helpful.

Good stickers. I'm using them kids' helmets, so car drivers can see them at dark time.

There are a lot of stickers in this packet... 101 to be exact. In the packet are a couple of flame looking and a skull with a flame, which I doubt I will use. But there are enough of stickers to last me a very long time. I got them primarily to put on my kayak and paddle. I don't usually kayak at night, but if I get caught out on the water at dusk, I want that extra reflection as a safety measure. So far, the adhesion is good. I got the yellow stickers for my yellow kayak because I didn't want them to be obvious... I just want them in case I need them. So I'm happy with them. I'm trying to think of other places to put them, like on a fence post near the corner of my property to headlights will shine on it. I saw someone mention putting the stickers on the garbage bins because they are left out on the curb. That's a great idea. Of course, if you have kids, there are so many places to put them. And the bikes and bike helmets would definitely get them. In short, they're working well for my kayak and paddle as a safety item. I hope there won't be any time I really need them to work, but if I'm out on the water at dark, I sure want to make sure I don't get hit by another boat!

I do a lot of night riding around my home, and I want to be as safe as possible. I grabbed these reflective stickers to put on my helmet and pads, and I'm super happy I did. They are ridiculously reflective, and cars don't have any problem seeing me. I feel like these add a layer of safety, and I think they're a good idea for any cyclists, skaters, or road runners spending a lot of time outside at night. The pack comes with a TON of stickers, so you should have plenty for whatever you feel like putting them on.

Just a little bit Reflective. It looked like black sticker.

Tested this product from different light sources and different lumens. From a flash to LED headlights these don't do anything from a 0.8 range to 150 ft. What a waste.

This collection contains reflective stickers of many sizes including about an inch to thin strips of more than 6 inches. The adhesion seems good, but I don't know if it will stay stuck with use. The reflectivity is moderate. You can get brighter reflectors, but they will be thicker. These are paper thin, making them suitable for many types of applications. My bike helmet has reflectors built in, but I have added a couple of the round ones from this collection. I have also used quite a few of these on the sides of my garbage and recycling bins, which are made of plastic. These bins have to be put near the road for the remote collectors on the garbage trucks to pick them up. It is always a worry that some car may veer into them. Having these reflectors on the sides makes the bins much safer.

These are very reflective, just lacking in the adhesion department. However, if you can get a smooth application it should stick as long as it's on a hard and smooth surface.
