Pretty impressed with these. Haven't had any fail on me yet and they always rupture along the line, although sometimes also around the top. Make a lovely loud bang. They are quite violent when they go off due to the pressure, mine shredded the cable ties and flew off a good couple of meters which was worrying as it could have hit someone but luckily it didn't. Have thrown a few of these and they work fine as normal grenades too.

Very quick to go off, great design, great for setting up trips or just lobbing
