Review: Very lightweight, easy to use and very affordable. - Arrived very quick! Easy to assemble. I bought it for my nine-year-old granddaughter. She loved it. It’s pretty cool how you can take photos with your phone! Comes with a very convenience backpack that everything fits in for easy travel.
Review: As advertised - great telescope! - I'm a complete novice, but this telescope was easy to assemble and use. The backpack it came with is a great selling point, and the adaptation for phones works well and has a very simple mechanism. Only fault is a loose screw that makes securing the prism somewhat of a challenge. I have solved it with a little masking tape and that works fine.

### ⭐⭐⭐⭐⭐ Very lightweight, easy to use and very affordable.

### ⭐⭐⭐⭐ As advertised - great telescope!
*by C***. on September 10, 2021*

I'm a complete novice, but this telescope was easy to assemble and use. The backpack it came with is a great selling point, and the adaptation for phones works well and has a very simple mechanism. Only fault is a loose screw that makes securing the prism somewhat of a challenge. I have solved it with a little masking tape and that works fine.

### ⭐⭐⭐⭐⭐ portable, easy to assemble and good quality
*by D***A on August 24, 2020*

This telescope is for my kid who is currently in preschool. My kid recently showed great interests to galaxy, planets, moons and stars, so I bought it as a gift for him. The telescope comes with a bag that is easy to carry. It took me about 5 mins to assemble it, which is much easier than expected. All pieces can be easily fit into the bag and you can carry it to anywhere. It's pretty light. Regarding the quality of the telescope itself, it did the work it described. Though you cannot expect to use this telescope to see the planet clearly, it can definitely gives you a clearer view of the moon surface, and you can see more stars at night as well. My kid is very excited about it and I'm satisfied with the quality as well.
