LEGO Technic Quality and Fun That Never Disappoints
LEGO never disappoints. You receive exactly what you pay for. While LEGO—especially the Technic line—can be a bit pricey, it is absolutely worth it. The quality, functionality, and attention to detail are excellent. What makes this set even more enjoyable is how it functions once assembled, along with the option to build it in two different ways. This adds extra value and replayability, making the building experience even more fun and engaging. Overall, it’s a fantastic product and a great choice for LEGO fans.

Dog ears are ugly
Was a bit challenging to build. Instructions weren’t the best, the dog ears look terrible so I removed them from the build. Tyres were a pain to fit on the rims properly. Of all the sets I’ve done so far this one was by far the easiest to use stickers with. Overall it’s a nice decent build and good challenge.

Great rainy day project
This required a little help for our 7year old but was just about right to finish in a day or two. Came with everything required to complete and of good quality. Finished product is a good size for a shelf.
