This is great value for price. Only downside is kids can easily push it over and break it.

Great stem toy for kids. My 8-yr old loves it. Pieces are durable. Click together easily.

Fun for kids who enjoy using their imagination and who enjoy making forts.

I would, definately, give 5 stars to this product if I did not have to go through some troubles with a quality, packaging, and a replacement of this product: 1. One plastic connector was cracked due to a manufacturing (molding) defect. Since I couldn't get a reoplacement for just this part, I had to request a replacement of the whole product. 2. This product was purchased as a present for a little kid. However, the shipper (Amazon, or whoever shipped this product to me) didn't bother to put the box in a plastic bag or, at least, protect the box with a shrink wrap film. They just place a bunch of self-adhesive labels on the original manufacturing box and shipped it. It took for me some time to remove those labels and clean the box in order to make it look like a present. I discussed a return/replacement and a quality of packaging with several Amazon CSRs (including a Team Leader or Supervisor); however, the replacement was shipped the same way, and I had to waste my time cleaning the box again. I am very disappointed, because, most definately, Amazon Shipping and Packaging team knows better. 3. The price for this item should not be more than $25.00; however, this toy, as well as many other kids' toys, is overpriced. Therefore: Product - 4 stars ⭐⭐⭐⭐ Price - 4 stars ⭐⭐⭐⭐ Packaging Service: 2 stars ⭐⭐ Overall: 4 stars ⭐⭐⭐⭐

The instructions are not the best but if you can build by looking at the picture then you'll have no problems, it's light weight and can be pretty sturdy depending on what you build and don't put heavy blankets over it, if the kids are too rough with it then it's probably going to break easily, there's enough room for both my kids to fit in most the builds they are 8 and 5 and on the taller side for their ages. It all fits back into its small box so doesn't take space when stored

Product quality is great and the extra pieces really allow for great constructions and creating forts with the kids.

This is very flimsy, and one of the pieces broke hours into play.
