Orzorz ستار بروجكتور بلس

I purchased the Orzorz Star Projector, Galaxy Night Light, Home Planetarium Projector with Rechargeable Battery but when I found that Orzorz made what sounded like a better projector, the Galaxy Lite Plus, I returned the Galaxy Night Light Home Planetarium Projector to Amazon and ordered the Galaxy Lite Plus with a set of additional slides. I assumed those additional slides would have projections of the Northern night sky and the Southern night sky. I have been disappointed for the following reasons:

I ordered the Galaxy Lite Plus Projector and the additional slide set. Instead, I received the Galaxy Lite Plus Projector and an identical insert, the one that already came with the projector. I received no additional slides. I still don't know what those slides would have shown. I would want to make absolutely sure that they show the constellations which I am teaching to my grandchildren.

The Galaxy Lite Plus rotates at a crazy fast speed. Even when I slowed it down to 1% using the app, it rotates way too fast and does not simulate the actual rotational speed of the night sky, like the less expensive projector does.

The meteor projections are very artificial looking, always occur in the same location, and occur way too frequently.

The less expensive projector could run on battery power. The Galaxy Lite Plus has to be plugged in. That is probably because it has a very bright light. However, I want to use it in locations where there are no electric outlets.

I've been trying to return the projector. Although Orzorz is an Amazon affiliate, this model could not be purchase directly from Amazon but had to be ordered directly from the manufacturer. Orzorz has no customer service phone number so I sent them an email. They have not responded to my email. It looks like I'm going to have to call Amazon and complain because these people are unresponsive.
