I didn't have much alternative, it was them or the Airsoft BB guns as a kid as there wasn't really anyone about with Air Rifles, I only tended to see them when I went to Yarmouth, I had the BB guns but for proper power it was the Slingshot as it could blow holes in things.
I won't lie when it comes to hitting the target, it can be a little tricky so best starting larger and close, then gradually working your way out and trying smaller things, you'll never guarentee a shot through a polo but you will hit a small can some distance away.
