Update: They got in touch quickly and sent another microscope to try and fix the problem. The oil I received was leaking again and almost empty and the instructions still didn't cover how to use the phone. However, I emailed the issue and they were able to email instructions. The instructions did not match the purchased microscope. The oil was almost empty. There was no second lens. Couldn't turn it on without proper guidance on how to use the phone. A disappointing Christmas gift if you can't use it.
