We picked up JB's Ghost Lab to check out the new theme and I have to say LEGO Team has really done a outstanding job! With new and fresh figures, pieces and the app interaction really makes this a fun set. I cant wait to pick up more set from the theme. The build is fun and easy with about 7+ stickers. I recommend really taking your time applying them on the wall pieces as they would be real hard to pull back up if they are not straight. I little trick I use is that I use a plastic tooth pick (new) that has the flattened end on them. This way you can get in the tight spaces without scratching the bricks. Then line everything up before slowly pressing down. Works great when you cant get your fingers in there. So I would say this is a great new theme and fun set and look forward to explore them further. On a last note, make sure you check to see if your device (phone, tablet) will work with the app. Happy Building

Recommendation: no 3.9 / 5 from 4 reviews

I loved this set for the science/spooky aesthetic, but be warned- this set is likely to cause upset children and annoyed parents. The app is only available f,or a limited set of phones and tablets (they are listed on Lego's site) but really that is academic. The app itself is unlikely to work once you have installed it. I have a google pixel and through reinstalling it multiple times and rebooting the phone I managed to get the AR part to work for a few hours. However, it eventually stopped working again. The theme is fun, but don't let your kids get into the app. It will produce frustration and misery. Also note- Lego sadly has a terrible track record of supporting their apps long-term. SIGH. Step up your game, Lego!

Recommendation: meh by Tim Johnson

Ultimately, this set offers a nice sample of the Hidden Side theme, and is perfectly serviceable as a playset, but disproportionately pales in comparison to other sets in the Hidden Side theme at slightly higher price points.

Hidden Side products have proven extremely impressive and 70418 J.B.'s Ghost Lab is definitely an enjoyable addition to the range, albeit not as enticing as some larger sets. The model features lovely detail in certain areas but the chamber for removing ghosts appears bland and should have provided some functionality in my opinion.

It may not be the most exciting of the Hidden Side sets, but it's a great taster of the what you can expect from the overall theme. I love the little features packed into such a small set, it may not have the same playability of some of the larger sets in the range; but if you wanted to give the theme go without heavily investing, this is the perfect set.
