I guess S-Thunder is still at it, pretty much aggressive sending sample units for reviews at various airsoft publications worldwide. After reviewing the water spraying landmine last May 2010, Airsoft International Magazine reviews the dual use landmine, which can either take water or powder depending on your preferences (somebody just whispered to me "urine" while bursting into a guffaw). Below is a review video review from IROPS Tactical Airsoft on the following:

• Step and Release mine
• Powder Spraying Mine
• Water Spraying Mine
• Shocker m203 Grenade
• Foam Ball m203 Grenade
• Dual cartridge co2 adapter with Regulator"
