bought this set for my 15 year old son, with the idea that he "played" with it with his 8 year old brother. before we had even had breakfast on christmas day, mum, dad and the two kids had had a shoot out!! great fun ,very easy to use , the 8 year old had no problems loading and shooting. the darts stick well to the vests and also to acrylic jumpers.if you get hit on your body it can sting a little on bare skin, but thats only to be expected and if you read the instructions its not recommended anyway. and the protective eye wear should be worn. only one criticism is that the velcro ends on the darts do peel a bit with use. replacements easy to get hold of and cheap though.everyone who comes to our house ends up having a play with them.not sure what neighbours think when they see me... a 42 yr old, overweight mum of 3 running round with my gun and ready for action!! as always,amazon offered a great price on this item, delivery was swift,even at christmas and the large item was well packaged.
