The Spark

Not as bright as some of their other offerings, but good for the price. Added as zipper pulls on a bag and they work well.

I have ordered the set of Spark glow fobs more than once. I use mine daily and they make great little presents as is, or as an add on to another present. They really help find things in the dark.

For a key chain or other fixed marker (like finding keys in a cavernous purse) it works great. It is smaller and, likewise, not as bright as the larger units, but it does work exactly as described and expected.
