Must purchase for little builders.
Wonderful!!!! Great set of building trucks and bird house. Easy to build by my 3-4 grandson. Very nice material and supplies. Heavy duty vehicles well made when done.. Can not say enough about this great kit!!

Good deal
Simple instructions my girl could follow. Everything where it should be. A good intro to hand building things.

Good Quality and Value
Happy with this purchase. This woodworking craft kit is pretty good quality, and the cost is reasonable, since 4 builds are included in this purchase. We got this item for our Cub Scout Pack (grades K - 5) and the build itself is mostly appropriate for this age/grade range. It takes the scouts about 30 - 40 minutes to build one of these robots, which is a perfect amount of time to fit into a pack meeting schedule. Minor critiques... the product says that it's appropriate for ages 3 and up, but in my opinion this build is best for ages 5 and up. Some parent/adult help is needed even for 5 and 6 year-old kids. It would have been nice if the directions and stickers for each robot build were "pre-sorted" (bagged with) the wooden building blocks instead of us having to sort these items into 4 separate groups. Also, it would have been helpful if the directions contained even just a little bit of text to help the kids interpret some of the step-by-step building images.

Great quality easy to put together
I bought this for my 5yo grandson. We had so much fun putting it together. The instruction were very easy to understand and the holes matched up perfectly. I will definitely buy again from this vendor

Awesome
Oh my gosh!! We bought these for our grandkids to build something with their Papa. They are just the right size. No hammering, everything was screwed in. The kids and Papa had a blast putting them together. The kids were so proud of their builds.

Look for parts
These were great. Only problem I had was that it was missing a lot of parts! You shouldn’t have to pay full price for something when there are missing parts. Fun for kids. Very durable because it’s wood.

My 5 yr old grandson loved it!
Stopped playing with everything else and wanted to put them together in the spot. Nice.y made and easy to assemble. Definitely a good gift!

My son is seven and he absolutely loved these. He wanted to do them on his own without any help, which he did. He was very proud of himself for being able to complete them on his own. Think they were a good happy medium in between. Tough enough that it still gave him a challenge, but easy enough that he could do it on his own. The directions were quite easy for him to follow as well. I would definitely purchase again

With my grandsons — aged four and six — coming to visit, I ordered a number of kits that we could complete in the workshop. Some were fine, some were pretty junky, but this set of four projects stood head and shoulders above the rest. The kits are beautifully designed and the materials, mostly solid wood, are carefully cut, drilled and finished. I was struck by the countersinking for the screw heads (also making piece identification easier) and the rounded corners of the various pieces. Overall quality and thoughtful details (the helicopter kit includes a Lego-like pilot) make this an outstanding bargain and a pleasure to work with and to share with my grandchildren. (The tow truck was so beautifully made we couldn’t bear to use the included decals, as neat as they were.)
