After completing Hedwig and Wall-E made by no-name companies, I was a bit sceptical whether the LEJI Ornithopter will be fun to build.
Luckily, the brick quality is rather good, there was nothing missing in the set and there were no malformed bricks.
After assembly, the set behaves the way I'd expect it to - there are no problems with the mechanisms, bricks are not falling apart or breaking, everything looks and works good.
The only small nitpick I could come up with are the "glass" bricks, they are a bit scratched and look a bit old.
Another thing is that the instructions often skip detailed description of steps and you have to very carefully examine every stage as some bricks are not explicitly shown as being added, they just "appear" on a finished product. Sometimes it was unclear which way the pieces were meant to be rotated or to what exactly they are supposed to be added to - I would consider it to be an advanced set.
Third slight issue is that minifigures are flimsy and are coming apart easily, also their equipment is different than in the instruction (e.g normal sword instead of krisknife). The stand Baron is supposed to be standing on is not working at all, I would probably have to glue it.
Having in mind how the set costs compared to the original, this is definitely a bargain, especially given that after assembly it is almost indistinguishable from the counterpart produced by the "known brick producer". The quality of bricks was good and I'm very satisfied with the end result.

Good quality bricks, only had 1 element with fittings too tight (swivel for the front landing gear, nothing a small file couldn't fix), and the Baron's cloak came crumpled and creased, but that was fixed as well. Good building experience, just a shame they kept the weird axle colors Lego used, would have made it better if they changed it, but hey it's a cloned set after all. Still highly recommended.

good morning,

I received your product very quickly and I'm very pleased with it. Your products are of high quality as well as your brochure/manual. I was pleasantly surprised by the little present hidden in the box. Bravo 5 stars.

Great Dealer

It was an incredible build incorporating technic style with block building. Very fun. The mechanisms may not be as smooth as L brand but it is right up there and for $100 less you can’t go wrong. Especially if you’re a fan of Dune.
