Perfect quality and prompt delivery.
The research chemicals themselves are exactly what I ordered and the delivery went exactly as the Professor promised.
The only (small) thing the Professor could improve is to better inform their customer service about the payment methods, because I asked them if it’s possible to pay in XMR which is short for Monero and the customer service said no, which caused me to worry because Monero is clearly stated on the website as a payment method, but I ordered anyway and everything was good.
I assume the person simply didn’t know that XMR is short for Monero, so that’s something they can easily improve but for the rest I have no complaints.
I am also thankful to the Professor for the free samples.
