This shoot your shot bullet is a decent size. It’s rather big which I think worked really well. I loved the dial at the bottom which was used to change the speed settings as it was so easy to change during use without the faff of trying to find a button. It was battery powered which I tend to not use just due to personal preference, I prefer being able to charge. The only other thing I would say is it is rather loud which isn’t an issue usually but if you live with others may be a slight issue.
