Query: Would not buy again

I must have gotten a crappy batch. I'd say only about 1 in 5 were "decent" which means they lit up for most of the stick and were a good brightness. Many (most) only lit up a tiny fraction of the stick and some didn't even light at all... so because of the better reviews, I can only assume the ones I got were lower quality or from a bad batch. They also did not come in a container that looks like the one in the photos that someone supplied... and yes, I cracked them the length of the stick and shook them vigorously, but shaking didn't help much.
