My kids have a few of the manual nerf rival guns and I absolutely think Nerf Rival is awesome compared to other nerf products. The system shoots farther, faster and more accurately than any of the dart-type products. So, when I saw this on sale for half price, I grabbed it. My advice: stick to the manual products. The way this gun works is that there is a small conveyor belt that rolls across the top of the clip dragging the balls forward towards two rapidly spinning wheels that propel the ball out of the gun. This causes several problems. 1. There is a lag of about 2 seconds from the time you pull the trigger until the first shot leaves the gun (after the first shot, it is essentially "primed" and this delay disappears for the remaining 39 shots but it's still annoying). 2. If you try to fire rapidly, the spinning wheels cannot get up to full speed between shots so every shot after the first one is at a significantly decreased speed which means it doesn't travel as fast or as far causing it to drop and it the target much lower than the first shot (it's fine if you pause between each shot, but that defeats the purpose of it being motorized). 3. It is noisy as all heck so there is no chance for a sneak attack. Add to all of that the fact that the clip is about a foot long and six inches wide making it awkward to hold and the fact that it takes six D cell batteries so it weighs something close to a metric-ton (slight exageration) and it becomes nearly worthless. I can fire faster, more accurately and more quietely with the manual guns with much less awkward use at a much lower cost. I won't take it back because it does work, but I wouldn't recommend buying it either (Get the Ner Rival Artemis instead).
