✅ Buy it if: You’re looking for a compact, affordable telescope that delivers excellent views of planets and moons and lets you capture those images with your smartphone (using the adapter). It is also well-made enough to handle a bit of rough use from beginners and youngsters.

❌ Don't buy it if: You're already a competent telescope user or if you want to view deep-space objects. For this, you'll have to spend considerably more for a model that can drink in light, like the Celestron Nextar 8SE.
