I bought this for my 5-year-old son and he loves it! The remote control is easy to use and the RC walker bulldog is quite sturdy. We didn't put the "bullets" in, because of his age, so we can't comment on that aspect.
This heng long walker bulldog is fun to operate and has made my son a happy boy. There is some small parts assembly that took us about 3 hours to complete, but the detail is nice and it runs great!
I think this was an amazing tank, good quality and It's a good Christmas present.
One of the most fun RC's I've bought in years, the plastic on the upper wheels & lower suspension mounts are brittle plastic so expect to snap a one and or the other but is easily fixed with a bit of sand paper a drill and some m2 screws. other than that I'm having great fun with it. I have also since upgraded the suspension, gearboxes drive wheels and tracks with hop up metal parts for that extra heavy duty look, feel and of course durability.
