Trich magnifying glass suggestions?

Hi all, wondering if someone can point me in the right direction for a decent magnifier on amazon? Have never owned one before and would like to make sure I harvest at the right time this year.
Much appreciated

I've had several but moved on to a USB microscope. I think ~$20 on Amazon. Make sure it's Android compatible.

This is what a USB microscope can show you...

Holy shit, that is detailed..never even heard of a USB micro, I will look into it.

Forgive me guys but these units are new to me... so I can take the scope off its stand, have it plugged in to my android phone, and see the results on my phones display?
I don't need to pack a laptop out to my greenhouse correct?

Find or buy a cheap $2 laser pointing and remove the focus lense! I have thousands of trichomes shots at great resolution. Just using my phone.
