Overall happy
I like the unit and agree seems a great value for the money. However:
1) User manual a little lacking. No picture with nomenclature call out, but if you're remotely familiar with microscopes or telescopes, you can figure it out. Oddly enough, when I googled it, I found what appeared to be an older manual with this exact feature !
Also got a little blue disk in a baggie. No description or instructions anywhere I could find on what it was or how to use it. Again, googled it. Just a blue filter that lays over light source.
2) The platform stop screw on mine isn't like in the pictures with a knurled top and locking collar. Mine is just a screw with an allen wrench socket hole in the top end. No allen wrench of this size included. Luckily I have lots of tools and found the one needed. Once set up your done. Shouldn't be an issue again.
I did call before I bought and they were friendly and answered my questions. Haven't called back as google answered my questions, late on Saturday nights.
Fulfillment and shipping was incredibly fast.
