I was kinda "meh" on this set but got it at as a gift and the gift giver clearly knows me better than I know myself. While not a challenging build, I really like the end product.

I wasn't aware when I got it, but the third one (the one with the stars in sky) comes with parts to allow you to change the constellation, which I thought was pretty cool.

Tempting. Still feels like a $30-35 set to me but it's getting closer. Thanks OP

This looks pretty good. Might complete it and then frame it on a wall.

Got this set and it's okay. I'm not a huge Lego fanboy so I'm not sure how it compares to other builds. This is was a not too complicated build but they do make a light kit that makes it a lot better looking but a little tedious.

I got this set the last time it was on sale. Very easy and a bit boring to build but I absolutely love the end result in my home office.

Was thinking a strong 25$ max. Love the 3D minimalist art though space theme is a large added bonus. So maybe 30$ max

Yeah the minimalist space theme is really well done here. I love the Lego Space stuff. But paying $10 per "postcard" still feels a bit steep to me.

Bought last night. Got it delivered this morning. I'm not a space enthusiast and didn't care about this set at all when it was announced, but the aesthetic kind of grew on me every time I saw it in stores.

However, Amazon shipped it in the manufacturer's box, just slapped a label on it. Fortunately it wasn't damaged during shipping and I was able to remove the label carefully but I wasn't thrilled with them doing that. The boxes can get dirty and damaged or wet, and I keep them for storage and resale value, plus it advertises to porch thieves. Any way to avoid Amazon doing this in the future?

There's a drop-down option at checkout something like "hide what's inside, ship in amazon box"
