This kept my granddaughter entertained on a rainy afternoon - she enjoyed it so much that she did it twice - there is a choice of 2 different small spaceships to make and the instruction book was very clear and easy to follow. The packaging is really good because it is bagged in sections then within the bag all the tiny bits are in another bag, also there are a few extra parts in case any of the main pieces are lost. This is a really fun Lego set.

My 9 year old son has loved every minute of building the grimkeeper set. It comes with 2 minifigures too; Cooper and Mateo. It's a very enjoyable and straightforward build, which he was able to complete all by himself. The grimkeeper stand at 21cm tall and has a cage in his torso! My son absolutely loved turning Z-Blob into a mini-plane or a hoverbike; he couldn't decide between the two and even started creating his own little inventions. The fully articulated torso, arms and legs, allowed me son to recreate different scenes and make the most out of playing with the grimkeeper! It's a fantastic gift for any fan and provides hours of play.

My daughter was super excited to receive this Lego set as she'd been complaining that she was bored! She couldn't wait to get started and decided to go online for the instructions rather than the booklet it came with as she found it easier. It kept her occupied for a few hours! The spaceship can be built 2 different ways and shoots darts which my daughter found fun.Both my children love building Lego, my son is into the speed champions and has collected most of them. I would recommend this set, now my daughter wants to collect a few of the other.
My 8 year old son absolutely loved to build this figure. He done in all by himself and he was very proud of how it turned out. He loves the mini figures as well. He commented on how lovely the colours in the character and figures are. He loves playing with it.
