Great!Bought it specifically for the shipping labels on plastic shipping bags. It was annoying to cut off the part of the bag with the label before throwing away the bag, just to be able to cut up the label. It is easy now to ink over the label before tossing it all in the trash.One star removed because you have to be especially careful that the cover clicks back over the roller else you will have ink residue on the case, then on your fingers, ....Completely blacks out info as advertisedExcellent product!Initially I thought this product was brilliant. When you roll over it really does cover up all your info. So what most people would do then is put the envelope/packaging/letter in the bin thinking everything is concealed by the ink. What I realised is when the ink is wet it does stop you being able to read what is underneath, however once the ink has dried you can read the info again. So after just a few goes I have stopped using this at all.I'll be honest, it is a piece of plastic that probably cost pennies to produce but I paid £6 for. But it works very well and the first thing I did was to obliterate the address details on the parcel it arrived in. Any reduction in identity fraud risk is worth £6 I reluctantly have to conclude. I've knocked a star off for the inky fingers caused by removing and reinserting the ink unit to see how refills work. It is not difficult to insert the cartridge incorrectly which results in a mechanical fault and ink where it shouldn't be to try and fix the problem. Note the position of the ink cartridge precisely when replacing and reinsert exactly as it came out. Operation is simple. Press the button on the top to retract the guard and expose and lock the inked wheel. Roll it across the text to be obscured. Press the button on the top to retract the inked wheel and drop the guard across it. I've got a DIN 3 shredder but there are things like jiffy bags and so on you can't shred where this will be invaluable. No regrets, wish it was cheaper.Ich hab mir von dem Produkt deutlich mehr erhofft! Sobald die Tinte vom Stempel getrocknet ist, kann man die Adresse trotzdem ohne Probleme erkennen. Im Nassen zustand sieht man die Adresse hingegen nicht.Sehr schade.Die Lieferung erfolgte schnell und reibungslos.Der Rollstempel reicht für ca. 50 m. Danach kann man einfach die Rolle austauschen.Ich bekomme zuhause so viel Post bzw. auch Werbebriefe, Pakete, die ich nicht mit meiner Adresse versehen ins Altpapier werfen möchte.Dieser Rollstempel hat genau die Breite einer normalen Adresse. Er funktioniert einwandfrei, z.B. auf Pappkartonaufklebern von Amazon, normalem Brief- und Kopierpapier, Kontoauszügen.Der Hersteller hat genau angegeben, für welche Papier-/Materialarten es nicht empfohlen wird. Daher finde ich einige Bewertungen hier sehr unfair.Für meinen privaten Bedarf ist dieser Rollstempel vollkommen ausreichend.Ich würde ihn jederzeit wieder kaufen und vergebe meine volle Kaufempfehlung.It's okay - kinda hides the private information but can sometimes need multiple applications and in different directions in order to completely cover it. I returned mine as I prefer shredding sensitive info using an office shredder.
