We got ourselves today 1/12 HY2M Air Shock Battle Beam Saber. This beam saber is the one used on the 1/12 HY2M RX-78-2. Though it was intended to be matched with the 1/12 model figure, it can also be used just for fun like teasing friends, Gundam role playing and etc. It has a scenario mode and battle mode to make it more interesting to use or for playability. Bandai has a microsite about this which you can find by clicking here. I think this is still available on online shops for an average price of $50 excluding shipping costs.
I would want to review this myself, but do not make video reviews. This is better seen on video instead of just looking at pictures…
