Fun Lego set
[This review was collected as part of a promotion.] My girls, ages 5 & 7, loved Cat Birthday Party and Treehouse set. Our household loves Lego products. The set has easy to follow directions, and the bags that come numbered make for an easy to understand assembly. There are no sharp edges or any worries that I have with the Lego sets.

Great LEGO set for cat lovers!
[This review was collected as part of a promotion.] We love the Lego Cat Birthday Party & Tree House set! My daughters (ages 4 and 8) have continued to use these as play sets, which means they get taken apart often. Luckily, assembly is so easy with this set. The different colors of each section of the tree house make it a snap to put back together. My only suggestion would be to make a similar Lego set that is similar to this for younger ages, as my toddler enjoyed the set most and required supervision due to part size. Still, it's a great set and also makes a great decoration for daughter's homeschool desk.

Great toy
[This review was collected as part of a promotion.] I got this for my nieces and they were so excited to play with it. It’s easy enough for them to put together without getting frustrated and the pieces are big enough that it’s not a choking hazard.

Hours of fun
[This review was collected as part of a promotion.] I received the LEGO Friends set, which contains 321 pieces in exchange for my honest review,and I couldn't be more pleased with the experience. This set is incredibly well-organized, with each section of the build packaged in separate bags that are numbered to correspond with the instructions in the manual. This thoughtful packaging made it easy to follow along during the building process, eliminating any confusion. My granddaughter spent hours immersed in building and playing with this set. Not only did she enjoy putting the pieces together, but she also loved letting her imagination run wild with the characters and scenarios. The set promotes creativity and problem-solving skills, making it a perfect addition to her toy collection. Overall, I highly recommend the LEGO Friends set for kids who love construction and imaginative play. It offers both fun and educational value, and watching my granddaughter enjoy it was a joy in itself!

New and Improved
[This review was collected as part of a promotion.] These are not the Lego sets from my childhood! The bags are numbered and so are the instructions with easy to follow pictures! I am not sure if I enjoyed putting this together more or my niece did. She will sure enjoy it for months to come as she played with it for at least an hour after first set up. Will be buying these Lego sets again for future gifts!

ABSOLUTELY PURCHASING MORE!!
[This review was collected as part of a promotion.] This is perfect for my 3 year old niece, kept her occupied and distracted while her baby sisters were sleeping. definitely recommend keeping it away from anyone under 3 for safety purposes. assembling is easy when it comes with instructions and pictures to show you where to put what. my niece knocked it down by accident but everything held together pretty well.

So cute!
[This review was collected as part of a promotion.] Absolutely adorable! Perfect for a cat lover or any Lego lover. It is a great addition and one of the better priced ones available. Assembly is easy and comparable to others in the Lego collection. There are small items just like other boxes but safe if done with a parent. It was easy and fun to establish.
