The quality of chinese product is up and down in my opinion. There are so many companies, it's not possible to give feedback on "chinese fireworks" it's just too broad..
In shells, star quality is number one importance to me. Next is symmetry, and third consistancy. Sunny, YF and Vulcan are the best ones I normally get to see.. and only some of Sunny are really good, many are just average. They have the capability to make great stuff, they just don't always use it!
Sunny
+ Fantastic star quality. Good colors, good streamers, good strobes.
- Unpredictable break sizes. Many shells are over broken, probably with flash assist which would account for why some are bigger than others.
YF
+ Fantastic colors, shapes and unusual effects.
+ symmetry is excellent, consistancy is excellent. attention to quality of finished goods is very good.
+ This is probably my favorite Oriental shell maker that I am aware of right now, without counting Japanese mfgs.
- Expensive. hehe
Pyroformex..
+ good consistancy, all shells perform in a predictable manner.
+ good symmetry, and bright stars
- too short of star duration in most cases
- colors are not as vivid as I'd like
What firework company do you work for, and what sort of feedback would you like to hear about? What process in the factory are you responsible for?
What types of things can you tell me about? Who are you seeing in China that is making the best products that we should be looking at?
