I am wondering whether I might of received a unit that had been previously used by someone. I'm not sure, but while the unit itself is sturdy and robust, mine was delivered with a missing lower halogen bulb! CS promtly sent me another bulb, and when I went to install it, I found the "original" bulb wedged into the space beneath the microscope. Other than that, I am satisfied. Customer Service was great.
This is a great starter microscope for kids interested in science. The only thing is you have no light it uses the reflection from a small mirror. That can be a little frustrating for both kid and adult. But everything else is great.
