Review for LEGO set 70754 ElectroMech from Brickset
“The completed model is great. The crossbow can turn up and down. The mech actually has a lot of poseabilty, which is something I admire in Lego mechs. You can put the mechs in various positions and still be stable. You can fire the stud shooters. Lastly, you can fold up or... More down the huge blade pieces. I think the set is worth it. For once I say this, the mech alone is worth it. I do appreciate the minifigures and the crossbow though. I highly recommend it to you, despite your age, as it makes a good collector's and a children's item.”
