After many hesitations regarding the choice of lightsaber that would please my grandchildren, I said that with this one I did not risk much given its low price. So I do not expect wonders and yet when I unpacked I am taking myself for Alice. It is just perfect: light effects and sounds changing when shaken and comes into contact with something; the sound can be muted. A week for delivery. I received this morning the 2 swords, 2 all work perfectly and I am now waiting to see the eyes of my little tonight. My only problem: stop playing with all the afternoon because I have work to do and that we should not discharge them before the little ones try them!
