(I have no comments about it.)

Reading the reviews, it's clear that a few are 100% CLUELESS about observing, which is how some are. Likely never read a thing about it prior to purchase. Plagued by a mediocre scope, only the really curious will survive it. The $17 Vivitar and Barska scopes are the bottom-end stuff. However, for those willing to forgo this junk, Meade sells a 90mm refractor on a reasonable alt-az mount for $220.00 now.

It even looks like a department store scope so it won't confuse the unwashed.

Looks decent enough. Have you tried it out in real life?

Anywhere much north of $200, I say save up for a 6-inch Dob.

A small refractor is far more robust and long lived than a Newtonian

I have never thrown away a Newtonian. I have a refractor that possibly shoukd be.



and requires no fiddly collimation or learning curve in use.

Learning.... We can't have that!

A 90mm refractor is a very decent instrument which can easily be turned into a bird watching telescope.

Word salad.



Assuming 'normal' optical glasses one should [ideally] be above f/10 to exceed Sidgwick's minimum standards for colour correction.

This particular refractor is an f 6.7, however.

It's easier to learn to collimate a larger Newtonian than it is to increase the aperture of a 90 mm refractor.
