Great Firecrackers

I like these firecrackers and will buy more. They have some duds and if you don't pull swift and fast they won't work, and they don't sound like one you would light. But i like them overall.

You Get What You Pay For

First off, despite the lack of quality in this product, I love BudK. I've bought a lot of stuff from here and all of it has been good until this one. I have tried only four of the ones I bought. Three failed. That is an unacceptable failure rate for anything other than maybe a toy, so I'm giving these to my boys to have fun with, hopefully they'll get more of them to pop. Bottom line: don't buy these for any serious purpose. I've read one review where a majority of these worked and it makes me wonder. In any case, while I am disappointed with this, I still recommend BudK, and I will be sure to read reviews of items before purchasing them.

Great for camping perimeter

Loud enough to wake you up. Great for setting trip wire around the tent when camping in bear country or elsewhere.

chinese garbage

Ordered 72 (6 boxes of 12) delivered in a timely manner. Opened one box and tried all 12. Only 2 went off, one with the noise of a cap gun the other was a dud and only fizzled. On all the string was rotten and pulled apart, had to use a pliers to pull the stubs left to get them to go off. Applied fire to the remaining that failed and of those 10 only 3 had any powder at all in them. Typical chinese made garbage.

Great for pranks

Had about 8/72 duds in my batch. I thought it was reasonable as there was no guarantee to no duds. Loved pranking my friends with these!

Cheap and Don't Work

I bought 72 of these which only about 12 worked. The ones that that worked where loud but the failure rate is not reliable! I would NOT trust these to be any alarm. They are fun when they work but I wasted my money on these. At least it wasn't that much money.
