Is a Longaoa 4k 10-300x40mm Super Telephoto Zoom Monocular Telescope for you?

This telescope is beginner friendly and allows you to magnify objects at a distance. However, it is not suitable for stargazers or astronomers. I have found it to be an invaluable tool when exploring the outdoors and highly recommend it for anyone looking for an affordable telescope.

What I Like About Longaoa 4k 10-300x40mm Super Telephoto Zoom Monocular Telescope?

I have been really impressed with this telescope. It is made of titanium alloy, making it lightweight yet durable. It also features an anti-shake system which helps stabilize the field of view while magnified multiple times.

The telescope also has a built-in night vision function which allows me to use it at night. It also comes with a tripod to stabilize the telescope further, plus a phone holder for taking pictures and videos of my view.

The instruction manual that comes with it was also very helpful and easy to understand which made using this product even easier for me!

What I Don’t Like About Longaoa 4k 10-300x40mm Super Telephoto Zoom Monocular Telescope?

What I did not like about this product is, it is cheaply made and flimsy. The phone holder is weak and the telescope lens has a very narrow radius. It took me over 35 minutes to take my first photo, which ended up being round instead of square.

Sometimes, the image quality is poorer than my cheapest binoculars.

Final Breakdown

I would rate it a 2 out of 10 for this telescope. Because, this is cheaply built and does not offer much in terms of quality or features. However, it is still a great value-for-money option if you are looking for something basic and affordable.

The build quality is poor and the materials used are cheap, making it prone to breakage. The features are limited and there are no bells or whistles that make it stand out from other products in its price range. Additionally, the performance is lacking compared to more expensive models.

Overall, this product may be suitable for those who need something basic and don’t want to spend too much money. It’s an acceptable choice if you’re looking for a budget-friendly option but don’t expect any long-term reliability or performance from it.
