Thanks to the weather so far I have only tried the scope for terrestrial use and I am astonished by the image quality. Its sharpness and clarity are well beyond what I expected for such a small and inexpensive telescope. The build quality is very solid and the included eyepiece is very good with no distortion or chromatic aberration. I also used the telescope as a lens for my EOS 20D and the resulting images were very good as well (it requires an inexpensive T ring adapter to hook the camera body to te rear of the telescope).
The included backpack is quite simple but gets the job done and it is the perfect size to carry the telescope tube, the viewfinder (unmounted), the 45 degree prism (unmounted) and several eyepieces.
The only minor complaint is that the included eyepiece included no covers so that when it is not mounted both ends are exposed and if it is mounted still one end is unprotected.
The viewfinder alignment is very simple and it takes just a few minutes to get it done and from then it does not move.
Complement this with a Celestron 8-24 mm 1.25" zoom eyepiece and you get a wide range of power to suit your needs.
UPDATE
There was a short break on the clouds some nights ago and I could watch Jupiter. Of course the image is nowhere near like illustrations from astronomy books but is quite a distinctive feeling to know that you are gazing at the real thing. I am sure that the atmospheric conditions were not great and because of that Jupiter came out as a small whitish circle but I could still see some color bands and 3 moons nearby. No luck with the moon yet.
Please get a decent solid tripod. I tried with a standard photography and video one and the result is quite bad. The whole thing shakes with the slightest touch on the focus knob. Fortunately I also have a Manfrotto tripod with a ballhead and this setting is much more usable but I still would ask you to get another head, a ballhead is far from ideal for this use but on the other hand is very solid.

Sharp little scope
I originally got this scope to serve me on a rifle range, which it does great. Fantastic contrast, very sharp picture, great color with minimal aberration. What really impressed me though is when I put on a Baader 90° diagonal and aimed it at the sky! This thing kills things in our solar system like the moon, Jupiter and Saturn, and I’ve also gotten some good views of the Orion Nebula. I was planning on getting a larger telescope for that, but I’m gonna save my money for now because this little guy does so well. One thing I’d HIGHLY recommend is to get a red dot finder to replace the magnified finder scope included, it will make your life a whole lot easier. Included is a picture of the first quarter moon and the Orion Nebula, both taken with this telescope, a Baader 90° prism diagonal, SVBony 40mm Plossl eyepiece, and a Celestron NexYZ mount holding my iPhone 13 using NightCap.
