I use this as an indicator of brass glowing. I've been using it for a while and it works great for this purpose. The last one I got was very bulky. Even after shaking until my hands hurt, it was an odd consistency with bits and pieces. It still works for the claimed app and doesn't seem to have much effect, hence the high rating.
