After my toner in the printer was empty I ordered through Amazon, the toner set of Hainsberger. Delivery very fast in a very large package. The toner was also still individually wrapped in bubble packaging. Damage is thus almost impossible. Expanded waste toner from printers and visually compared with the new toner cartridge. Absolutely identical. No cheap plastic. Toner used in printers (CLP 320). The cartridges were detected immediately. The expression for the degree of filling in all the cartridges is 100%. The pressure Verleich with the original cartridges shows no differences. The empty cartridges I will return the next day to Fa. Hainsberger. There are a reimbursement. Rücksendeschein is. In sum, I am very satisfied and would recommend to all buyers the cartridges with a clear conscience. Short delivery time, quality class, return of old cartridges - what more could you want. Strong buy recommendation.
