L'Antre Du Dingo takes a look at three T238 40mm airsoft grenades: the Matrix, the Spin, and the Hexa. All three grenades are activated by a launcher, have integrated RGB and UV LEDs for a tracer and "flame" effect, and are powered by a rechargeable USB-C battery. They are made of anodized 601 aluminum and are priced similarly. The Matrix can launch different projectiles, including reusable foam balls, and has a mini-switch to indicate when it's armed. The Spin holds 50 BBs that disperse widely, while the Hexa has six compartments, each holding 8 BBs. He says that while the range isn't impressive (8-15 meters), they are fun for close-quarters engagements and offer a good sound and light effect.
