Ive bought a good deal from explore scientific and honestly, am very happy with everything they put out. Overall the scope is sturdy and the burgandy color really makes this one stand out from other dobs on the market.
The dob itself feels very sturdy and well-made. Not a single loose bit on it. When i got my dob there was a small bit of mystery oil on the outside of the tube but rubbed right off. I did manage to get first light on it the night I put it together and it came very well-collimated even after bumping around in a mail van.
The primary mirror did come with a small, roughly 1/2 inch smudge but im 100% positive it has no negative effect on my views. Something super minor.
The worst thing about the dob is the red dot accessory if you can even call it a red dot. It is so poorly made. The red dot lens itself is very dark so when you try to look through it you cant even see the stars. Just throw it away and dont waste your time on trying to make it work.
