Let me start by saying, this little astronaut projector has been a game-changer in our household. As someone who's tested multiple star projectors, the FlyLily Galaxy Projector stands out with its unique slide-based system and adorable design.

The moment I unboxed it, I was impressed by the solid build quality - much heavier than expected! The magnetic astronaut head is genius, allowing for easy angle adjustments. My personal favorite feature? The crisp 4K HD projections that actually look like real celestial bodies, not just blurry blobs of light.

Using it is incredibly simple: pop in one of the 13 included discs (I'm partial to the Milky Way), adjust the focus knob (which does require some tinkering per disc), and enjoy. The slow rotation creates this mesmerizing effect that's perfect for bedtime. My niece literally gasped when she first saw Saturn projected across her ceiling!

Now for some real talk - it's not perfect. The nebula projections can look a bit distorted unless you're directly underneath them, and you do need complete darkness for best results (no daytime star-gazing sessions). Also, changing discs requires getting up - not ideal when you're already cozy in bed.

The rocket nightlight feature is a nice bonus though, with its color-changing options. And the auto-timer (1-4 hours) means I don't have to worry about leaving it on all night. Pro tip: position it centrally in your room for optimal projection coverage.

At its price point, I'd say this is best suited for space enthusiasts or parents looking to create magical bedtime experiences. While cheaper options exist, none deliver this combination of educational value and visual quality. Just be prepared to explain why Pluto isn't included!
