I bought this bionic eye at its full price $40 last year, that was after I almost paid $400 for a similar system at LA science museum. I think it well worth it if you plan to introduce some basic science knowledge to your kids at home.
Having that said, as the other reviewer also noted, my 4 years old showed little interest. It’s tricky to focus and hold the sensor steadily so that you have a meaningful image on the TV screen.
They know have a second generation item which comes with its own LCD display. I bought that too, immediately, but it still sat in the box after about a year. I am still waiting for my child to develop interests and curiosity in exploring unknowns.
At today’s sale price of $5, it definitely worth every penny. I am going to buy a few to donate to daycares in the area.
