Troll

Every display needs a bit of mischief, and Troll is happy to oblige. Fifteen shots of fast, bright colour packed into about half a minute, a cheeky little garden cake that stirs things up nicely.

From Gemstone, F2 rated, so 8 metres is all the room it needs. Quick to fire, easy on the wallet, and a proper splash of colour for not much money.

Let the little troublemaker off the leash. At under a tenner, it punches well above its weight.
