I am going to try my hardest to keep this polite, but when you light the Thunder Blitz, you are probably going to shout a few choice words.
This is absolute madness in a box. It is a heavyweight 1.3G compound that packs a massive 1880g of powder into 100 shots. That is nearly 20g of explosive per tube, which explains why the bursts are so violent and the noise is so aggressive.
Lasting around 75 to 90 seconds, it doesn't rush. It hammers the sky with a relentless display of huge breaks and deep, chest-thumping thuds. If you are looking for a standalone piece to make a statement or a finale that leaves people stunned, this is the one.
Galactic Top Tip:
This is a compound firework, which means two individual cakes fused together inside. However, you will often see two fuses on the outside—a Primary and a Reserve. Only light the Primary fuse! The Reserve is strictly a backup plan if the first one fails. If you light the Reserve first, the display will fire backwards and the finale will happen at the start!
