## Customer Reviews

### ⭐⭐⭐⭐⭐ Lego Juniors speed radar kit with gray Lightning McQueen and the Sheriff
*by I***R on June 14, 2017*

This is a Lego Juniors kit consisting of 95 pieces. The kit contains Lighting McQueen in his gray training outfit and Sheriff. There is a “radar” speed detector on a trailer (which can be hooked to one of the cars and towed via the tow bar. There is also a ramp and a roadblock (has two swinging barrier bars) a cone and a shrub.With Juniors kits, some pieces are already put together (such as much of the chassis and the tire pegs.) There are no stickers in the kit as all of the features are already printed on the pieces. My grandson was able to put most of the kit together (though some pieces were a little more difficult such as the speed detector.) He's not quite four, so it should be fairly easy for a slightly older child.

### ⭐⭐⭐⭐⭐ Nice Cars Lego set
*by V***G on July 29, 2018*

Very good for a lego loving 4 year old. The car bases are already built making the builds very easy. My son loves the Juniors sets but they have gotten easier for him since he has built so many. They do get easy after building so many. But a very good start for a 3 or 4 year old. Definitely too advanced for a 7 year old.

### ⭐⭐⭐⭐ It was open box..!
*by J***Z on February 8, 2019*

Clearly..! It was open box..! I’m very upset..! I did not return it because I couldn’t wait for another..!
