### ⭐⭐⭐⭐⭐ Satisfied customer
*by D***L on January 21, 2026*

Perfect gift for a 9 year old boy.

### ⭐⭐⭐⭐⭐ Lego-like robotic car
*by R***S on January 1, 2026*

Hmmmmm... .. . Where do I start? We bought this robotic item for our 10yr old grandson who is a 'Lego-fanatic'! It took him less than 5min to decide he didn't like the gift, ie, the bags of parts were not paired well with the instruction booklet, which in & of itself was not very explanatory. Sooooo...I, his 74+yr old grandfather made him help 'me' assemble roughly half of one vehicle which took us half the day. Then...he was done! I plan on trying to complete the project at some time in the future, but it will happen without his assistance.
