Trying an experiment with a mini-turntable (6" diameter). I leveraged the GRS "Slide & Lock" to obtain a comfortable microscope viewing height. We'll see how it plays out during my early learning days. The turntable is stable and turns easily but can be tightened for more rotational resistance.
I couldn't confirm my email either. I switched my address from GMAIL and the issue was resolved using my Apple iCloud account. Gmail rejecting emails appears to be a problem for a lot of users.
