Can you provide pictures for assembling? I believe I’m missing parts – but, I’m not sure what the parts are supposed to look like. I’ve had this for 2 weeks – and not able to use it. It would be very helpful as I found the directions are very poor. This isn’t very complicated if you know what things look like. What is “remove one cap from the base” – what is the base? is that the square metal box with holes cut into it? What is a diffuser? If I have these questions, then others do as well. This could all be simply addressed if there were photos to accompany the instructions showing how things fit together. It is very frustrating, and disappointing – and, something one would expect for the price paid.
