Brick quality: Kazi was always average at best, so I didn't expected much. However, this is 2023 set, so I can definitely see some progress. The pieces look nicer, the transparent ones even look great! The clutch is not consistent, but nothing is too tight or too loose. The tolerances are obviously bigger than those of the top brands, it results in bigger spaces between pieces, but it still doesn't look too bad. The biggest concern was, of course, the quality of the technic pieces, would they be able to work at all? But in the end, everything is working as it should.
Design: despite of how small this set is, it's probably the most complicated mechanism I've ever had in Lego. The Sun is rotating, the Earth is rotating+rotating around the Sun, and the Moon is rotating around the Earth! PLUS the Sun has a lighting element inside, which is quite bright. They made Sun "surface" variated with transparent red, yellow and orange pieces, even added a dark sunspot!! The element representing the stars is just "put" on the final build, it's not really holding. Strange decision. And of course colours, technically I agree that there are plenty of colours in space, including stars and planets, however for such a small set there are just too much (my wife actually hates it because of this, says it looks too childish).
Stickers: I've never had a Kazi set with stickers, there were always prints. But this one has 2 huge stickers, each goes over 2 pieces. The stickers don't seem too reliable, their quality is questionable, it's hard to describe as I've actually never seen stickers like this before.
Instructions: easy to follow, too big and look cheap. The Sun part was the most complicated one and I actually built it differently, in smaller steps because following the instructions would just result in it falling apart every time trying to connect new pieces.
Overall, the series are great, with clever technics and mechanisms, so if you're not afraid of the quality and are ok with colours - go for it.
