Brilliant quality
This is a brilliant building block (lego dup) set. I was very wary about this when I brought it because its obviously not lego brand. However it is very good quality. The instructions were clear enough and similar to Lego instructions. There was a small mistake in the number of blocks needed in one step however the picture showed how wrong it was and it was easy to rectify. This small mistake is nothing really and the finished product is awesome. Its sturdy and looks very realistic. My 12 year old loves it.

Something a bit different
I really enjoyed building this model it was very interesting. I wasn't sure if it was going to be stable enough but it is pretty solid. I wouldn't swing it around but as a display model it looks great. Took a fair few hours to build as it is very fiddly. I use a couple of pasta bowls to organise the pieces as some are tiny. I found this a challenge to build but very therapeutic whilst listening to my favourite podcast. Good value for money as the model is actually bigger than I originally realised.

Good product
Overall very good product and pretty cool however there were a few pieces missing and due to the box being damaged some of the stickers were too creased to use but overall pretty good :)

Cool
Brought this for my husband. He loved it. It was a great price and a fun build for him. Its good quality too. Quite large but looks great in a shelf.

10/10
Honestly great, was missing one piece but managed around it and can thankfully hide it by just facing the stand the other way but it was fun to make and looks awesome completed! As an avid anime fan, I was really excited for this and now I can’t wait to get the next one and eventually the whole set.

Highly recommend
A work of art, quite literally! This was brought as a Christmas present for my daughter who loves demon slayer. Although the aim was for her to build it she started it off and got frustrated so I ended up building it and I just couldn't believe how fab the design was! If your child loves lego type stuff this is brilliant, if your after some brain work this is great too. Highly recommend!

Actually really good
Boy is 12 he loves it, found instructions hard as little smaller to Lego. But he got done he thinks its grate and considering it's length and width holds together well. He is thinking he wants to glue tho. He also thinks it's better without stickers. His only real complaint was it didn't make the same click sound when click together so was as satisfying as Lego 🤣
