This kit is well thought out and worth the price. However, if you are serious about microscopes, know that this is more of a toy for a 5 year old, and that's it.
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.
