Someone gave this to my son for his birthday and he was excited while opening it. Then we realized the bulb was not working, which made the entire microscope unusable. I wrote to the company and a customer rep promised to mail us a bulb. That was 4 months ago. We are stilll waiting. Clearly they do not make good on their products. This one should have been taken off the market.
