Things I liked:Price for performance is great, weight is manageable for my 9 yr old. Things I would have changed:give option to buy refillable bottle as pkg deal or choice of hpa. Would be worth the extra $. What others should know:very accurate. my son hits golf balls at 25 and 30 yrd with some concentration. I hit them at forty off hand 3 of 5 shots. This a great starting platform to teach marksmanship as well as air gun theory. my 9yr old will have lots of years of learning from this until he can build his own custom rifle. Lots of possibilities here.
