A little difficult to put together but nice quality model for teaching

Some of the pieces were super hard to snap together. Once snapped together, some of them broke easily when twisting the model to make the double helix shape, and when i accidentally dropped it one time. Overall it looks great and gets the job done besides that.

It’s near impossible to snap the pieces together. Lots of pressure and some just won’t fit.

Its great. My son really loves microbiology so learning about the cell and its organelles and all the way down to the atom, is enhanced when we can explore touch theory in our learning. Warning though I thought I'd smashed every one of my fingers tips after I was done. Like I ran them through a blender they hurt so bad. Its hard snapping these little pieces together but they stay strong for at least 3 months with an active 4 year old.

This is a small plastic model that only has directions in Chinese characters. You need to already have a knowledge of genetics to use this model. I suggest its value in the 4 to 5 dollar range. You would be well served to purchase a set of pop beads to make this model. The parts don't easily snap together. I had to get a pair of channel lock pliers to force the white balls into the black parts.Amazon should remove this product from their store.

I couldn't read the directions, because they were in Chinese.

I ordered this for a display case. The parts were incredibly difficult to put together, and I hurt my hands trying to snap together the backbone. Like others said, directions are in Chinese only. I was able to figure it out based on pictures, but overall I am incredibly disappointed with this product.

There were no instructions as to the joining of the 4 DNA components
