I ordered the product and it arrived a little faster than expected, when I arrived immediately ko saw and I really liked the presentation of the box is excellent, This toy comes very well packaged, each dinosaur crib with its own space and bag inside the box, and the instructions easy to follow for the assembly, it is easy to assembly with of children, and the tools are the perfect size for their hands, I bought it as a gift but assemble it together with the child, it is an excellent gift.So fun and easy to put together and take apart. They are perfect for any age just make sure not for little babies or toddlers because it has small nuts and screws. The kids all love these. A great set for any childGot my granddaughter for Christmas. She loves playing with these. Still a little challenge for her to put together. Would buy again. 3.5 yrs old.These dinosaurs are wonderful for many different age levels, but for my 11 year old, special needs grandson they are terrific! He loves dinosaurs and the opportunity to assemble & re-assembly these will greatly improve his eye/hand coordination.It is a good STEM toy for my kid. My girl loves dinosaurs. She is age 3, and she can assemble these three dinosaurs with some help from the adult.I got this as a birthday gift for my child, The instructions were clear and the toys were relatively easy to build - great for fine motor skills and hand/eye coordination skills. However, it was frustrating because 2 dinos were missing pieces so they remain incomplete... which defeats the purpose.Loved the product, not happy about where to get the matching tail - from ChinaMy boys enjoyed putting these fun toys together. Each dinosaur came with its own screws and screwdriver. The whole set came with a drill and drill bits. Was easy enough for my 5, 6 & 7 year olds to do. Took about 10 minutes. Teaches problem solving. They like that each part on the dinosaur moves! The picture is different from what you actually get but I liked what we received better. Only issue was several of the plastic screws broke easily. Overall fun and good stem toy for kids!
