It was my husband’s birthday yesterday and as one of his presents I gave him these cool mini tanks from iwantoneofthose.com. The tanks have infra red guns and when you hit your opponent their tank spins around before becoming invincible for several seconds. Each tank has five lives, once you have been hit five times you need to reset the tanks before starting another game. After playing with the tanks for nearly a day and recharging them several times (battery life can be a little short) we discovered it was very hard to hit your opponent. We eventually realised that we had forgotten to remove the covers over the sensor points on the tanks although the instructions supplied with the tanks don’t appear to cover this. Anyway sensor covers removed and we were happily shooting each others tanks on our improvised terrain made of CD boxes.
