This scope has been around for nearly two years. Reviews aren't great,
but typical for the price and wide field. Google is your friend.

That's what it says, rich-field!
But is it flat field or what?

Just a plain Fraunhofer achromat and a fast one. Will have a bit of colour, not great for planets.

No rich-field scope is good for planets!
Made for photo and wide fields!

The only real innovation is hiding the star diagonal in the main tube.

Fast refractors and wide fields tend to be demanding on eyepieces too.
There is no free lunch.

-cut-

This isn't what I would choose or recommend for the price shown, but I wouldn't pan it either. The inclusion of the 7x50 binocular is problematic, because the FOV isn't specified. The eyepiece might be nice to have, at 70-deg AFOV. You get a case too. Maybe the tripod can be used with other equipment.

I would rather a beginner get a larger-aperture Newtonian and a binocular of his/her own choosing.
