Nerf Star Wars Amban Phase-Pulse Blaster

Edit to review: Second unit wasn't broken. It was user error. Testing the second unit without attaching the barrel made it not work. I discovered the mechanism that needed to be depressed by the barrel attachment only after receiving the 3rd unit a day late for my son's birthday. Oops. Bought for my son's birthday a few weeks ago. On a whim decided to put it together to wrap without a box. Tried it after I put the two pieces together since I didn't read the reviews first. The breech wouldn't pop up like the instructions said. But I loaded it and shot a few rounds and it seemed to shoot pretty well. Then I finally noticed the little spring mechanism was loose cuz the piece you insert the dart into was broken at the base. Ok. Must return for a new one, luckily it's still a few days until my son's birthday. Rigged the box for returning since the gun is now nearly 5ft long. Got replacement today. Excited to try. Didn't put the long barrels on this time cuz I learned my lesson. Excited the breech popped right open like it was supposed to. Wouldn't fire. Pulled the trigger multiple times before the dart flew out (pretty true, however). Tried again and again and again. Fired when I tapped the side of the buttstock. I kept hoping the trigger which felt like it was attached to a rubber band that's pulled too tightly would maybe loosen up and fix itself. No dice. I wanted it to work so badly, but finally gave up. Son's birthday is on Monday, and that's when 2nd replacement is supposed to arrive. 3rd try's a charm hopefully. I'll update this review with whether I get a working unit.
