Query: Fun for Kids, but Check Thoroughly

I ordered one of these for Christmas for my daughter. Unfortunately, I didn't check the box before Christmas Day. Turns out, the one we got was missing the eye piece. Unusable without. So, I sent it back.The next one I received had the eye piece, but the light switch would not easily turn on in position two. After some use, it got worse, to the point we couldn't turn the light on. So I returned it again.The third one is fine. No problems. I also bought two extra to give to my daughter's science teacher, and those were fine as well. So just be careful and check when you receive it.
