"Despite my initial skepticism, the quality of NERF toys turned out way better than I expected. I have to credit the creators as it is clear that good thoughts have been put in to produce practical PLAY-ABLE toys. Meaning.... neither Frodo nor I are going to break the toys any time soon.
To get the ball to light up:
-No battery required.
-The human can shake it to get it to light up - on this note I must say that the Barbell lights up easier on one side. Maybe mine is slightly faulty/wonky... I don't know!
-You can throw it/bash it on the ground and ber-bling ber-bling.
-3 ber-blings - Red, Blue and Green.
The Barbell was fun to fetch BUT
-with its weight, it was pretty cumbersome to throw;
-it had a bit more limitations in terms of HOW we could utilise the toy. We could not do the "off-the-way' throws... gravity dictated that it bashes straight down to the floor before it could hit the wall;
-even though both Frodo and I could effectively fetch the it back, we preferred fetching the ball;
-we could play toss-and-catch with the ball."
