### ⭐⭐⭐⭐⭐ Kids love it.
*by T***2 on August 4, 2020*

Great instructions and well designed. My 6yr old son loves it. The remote part of it is a little slow and weak however for the price it's one of the best kids presents available. Thanks Amazon.

### ⭐⭐⭐⭐⭐ Love this
*by C***P on September 24, 2024*

My son adores this toy. It's one of his favorites. It was reasonably priced too so you can't beat that.

### ⭐⭐⭐⭐ Good for Budding Little Engineer
*by R***G on August 2, 2020*

It's a gift for my soon to be 5-year old boy. He loves to build things and I expect he will love this. He's still young so I think the large size will be great. It's definitely far cheaper than similar Legos or Erector Sets. It reminds me of similar non-name brand toys I had growing up, and I became a mechanical engineer. I'll update after he opens it and gets a chance to build.
