The Weco "Rio" rocket pack from Aldi, £19.99 for 18 large rockets. Works out about £1.11 per rocket, which is pretty good in my books.
You get:
7 "Atlantis"
6 "Challenger"
5 "Discovery"
All boast a "shell burst" effect.
Descriptions of each rocket are as follows
Atlantis - Circular shaped silver to red chrysanthemum shell burst
Challenger - Circular shaped bright silver chrysanthemum shell burst
Discovery - Circular shaped ruby red chrysanthemum shell burst
Now a couple of pictures


I'll write reports of these once i fire them and hopefully get some videos to upload aswell. Im sure i had a couple of the Atlantis rockets last year and as far as i remember they were impressive.
