The kit is priced right and easy to build, and the completed rocket flies great. I very strongly recommend this as a first kit for any kid, although participation in the build by an adult/experienced rocket builder will improve the results.
My only nitpick about it is that the stock decal job seems have not been fully finalized before the kit went into production. Several of the body wraps are the wrong size, either are too small to wrap all the way around the body tube or large enough that they must be trimmed to fit. It’s possible, pretty easy actually, to get the rocket to look like it does in the most prominent photo on the packaging, but it’ll only really look good from that angle. It will also mismatch a few of the other photos, which I believe are actually photos of a different example with a different sticker arrangement.
Like the manufacturer, I’d advise a completely customized appearance. If you’re building with a child, let them go crazy with markers or paints or whatever they’d like that won’t be too messy. They’ll end up with something unique and have a bit of a reward for being patient with the build process.
