I bought three pairs of these laser tag guns as Christmas presents for myself, my brother, and my cousins for us to share. I already knew what to expect, and I had a feeling they'd enjoy it as much as I did when I first played with them. I was right. So after playing a few rounds, here is the main thing to keep in mind if you decide to purchase these toys: The shock is real. I found that the more you get into the game and increase your adrenaline, the less painful and noticeable the shock. But you will feel it, and the high-shock setting can be a little painful. The initial shock, when set on low, isn't exactly the most pleasant feeling in the world, but it is bearable. I'd describe it as the feeling of your arm falling asleep, and then hitting it against something. It should be alright for teenagers (around 15) and older. It may be a little on the expensive side, but if you know that this toy will be used frequently, then I think it's worth it.
