What you are selling is not comparable to the nerf ones yours does not go strait they are smaller and lighter which is why I think it causes a problem when you fire them they go left right up down not one goes strait
My nephews don't seem to mind the shortfalls of these new bullets at all. All they know is that they don't have to search the entire house for the lost bullets. At least they don't have to do it yet since this is a 100 back. Overall I feel like these are perfect for my nephews who are 8 and 6 years old. But I feel like if they were much older they might not like them very much at all. I gave them three stars because my nephews really do like them despite what I found wrong with them. I bought this product at a discount price in return for an honest review.
