Pros:   *Product works as expected (or at least performs as it is intended for my use, coloring spots on developed TLC plates). *Price, even with US tariffs, are better than what US suppliers to residential customers charge.  Well known chemical suppliers in the US will not sell to residential customers and go as far as preventing their distributers from doing so as well due to liability issues. *Fast shipment. Cons: *DDP/import/tariff charges were not fully accounted for so had to pay additional fees to UPS upon delivery--would have rather had this handled right in the initial transaction.  Again, total price still better than from US sellers. *Product starts to degrade at temperatures above freezing (ideally store below -20C/-4F).  While it was packed slightly insulated with cold packs, it was not sufficient, as it was room temperature by the time I recieved 2 days and 9 hours later.
