Going to share my experience. I bought Lepin 05028 Superstar Destroyer about a month ago. The parts are all good but it got quite a bit of missing pieces. The part rounded in red circle about 90 of them is missing (total in this model is around 140+). I'm requesting for the missing part from the seller (one of the shop in Amcorp) it should be here in few days.

Here is the roughly finished product. The plastic is softer than LEGO sets and usually very easy to disassembly, and because of this the long parts are easily warped. But it is sturdy enough and not fall apart even on this very long model (1.24m in length). The leg is very sturdy and you can transport it easily, just mind the length.

The other model I bought yesterday is Lepin 05046 Rebel Blockade Runner. This is one of my favorite UCS set that I really wanted for a long time. This time I got a few extra parts, and two defect parts (one looks like it's been compressed and the other is not enough plastic on the block) but I can hid the parts easily so it's a non issue. Here is some of the extra bit.

But this have LEGO flaw as well, the part is build in sections, and the worst bit is the massive 11 engines is so damn heavy I spend 3 hours on top of 8 hours trying to fix the engine mounting properly. First time it simply disintegrated when I lifted it and after thorough look in the manual I made few adjustment and add some parts from the extra bit to make it sturdier. The engine alone have 15 sections that needs to be attached to the main engine structure (the 11 engines, 4 attachment for outboard engine left and right side).

The finished product is absolutely stunning

I cannot imagine I'm having 2 UCS inside my room right now. If I bought LEGO set would fetch me more than RM10k, I didn't even spend close to RM1k for both Size comparison for both sets.

I'm planning to buy the Imperial Star Destroyer next but I'm out of room to place it. I bought it for nostalgia sake, I dream of having these set since high school when it was released. Thanks Lepin for making my dream come true and no thanks to LEGO collector making these set price sky high
