Cool
Cool set it came fast was exactly as described all parts accounted for. It's a major brand so the quality is great directions were clear. And can be used with all other of the major brand.

Great set and good app
Great set! There is a lot of detail and my 6 year old loved putting it together. There are a lot of negative comments about the interactive portion. I think this is very family dependent. My 6 year old plays almost no video games so getting to do this was a real treat and she loved it. Both my husband and I enjoyed playing it with her. I’m not sure how many times she’ll want to play but for a a very reasonable price (especially for Legos) and an afternoon of fun we give this 5 stars.

Simple and fun set
Bang for buck, this is probably the best Hidden Side set. We bought it a couple of weeks before Halloween. The tree portion is a really fun and creative build. We have the dockside shrimp restaurant one and the AR on it was just OK, as such, we haven't tried it on the Graveyard, so I can't speak to that. But the build was fun and my 8-year-old daughter likes playing with the set.

Cool cemetery set
I purchased this to use along with baby calico critters in a stop motion video. This took me longer to put together as I had issues with finding the right pieces, thought a few were missing, but they were not. The dog is very cute and looks awesome, and the skeleton guy is neat! The LEGO haunted cemetery is great, just not having any luck with the app, not a deal breaker, but would have been nice to add to my video. LEGOs are fun to mess around with when the weather is nasty out. Yeah I’m an old fart monkeying around with LEGO’s but it keeps my mind active and have a lot of fun making stop motion videos . This would be great for anyone into legos to add to their collection.

Perfect Creepy Scene Setter
This is a great Lego Graveyard scene set. Even if you are not used to, or buying this for the purpose of, using the mobile app to scan for and collect ghosts this set is a great value for its cost. It is full of moving parts, from the open graves, to the building, to the gates. I actually am using this for a graveyard scene beside a Lego haunted house (like Monster Fighter Series - 10228). The tree actually can be disassembled for spooky eyes and the branches and roots make great creepy vines. Playability: 4.5/5 Value: 5/5 Ease of Assembly: 4/5 Various Uses: 5/5 (Graveyard, Old Gatehouse, Interactive Game, or Creepy Church)

Pretty awesome
My son loves legos, zombies, skeletons (pretty much anything halloween) so this was a perfect fit. He wants the whole collection now of course. Quite an extensive setup for a $27 set. Lots of fun figures and moving parts. We did connect with the app which worked pretty well. He's not quite old enough to understand the game (he just turned 5), but for 7-12 year olds I think they would really enjoy the app experience as well.

Muito bacana. Como sempre, o manual de montagem é incrível e de fácil compreensão, mas como a montagem tem uma certa dificuldade a criança pode precisar de auxílio para montar. A surpresa do meu irmão foi a realidade aumentada, ele ficou encantado e horas brincando. Recomendo!

Really fun to use with app. After a little training, my 5yo was able to use it by himself no problem.

Una Pena que NO detallen en la caja los dispositivos compatibles. Tras comprarlo no he conseguido instalar la app (y tengo en casa 4 móviles y tablet). Lo peor es que consultas por email a lego y no responden. Lamentable que una firma como lego no tenga un servicio de atención al cliente efectivo.
