There have been a few problems due to long distance transportation. But I fixed it myself, it's okay. Shop has very good support.
I ordered a microscope Amscope T690C-DK-PL specialy designed for darkfield microscopy but you sent a cheaper T690C-PL with a darkfield condenser that doesn't fit the mounting ring on the microscope and so unusable. It's not the one suppose to be. I, specifically ordered a darkfield version for my work and I can't use it !!!! I intend to do a dispute.
No answers from that seller. Juste a ridiculous refund. Don't buy anything from that seller.
