I already had this product and was very satisfied. It represents a favorable alternative to the brand-name toner from HP. Own a HP Laserjet Color MFP M175a 100 and works with these toners to my complete satisfaction ... Mention should also be that I delivered equal to 2 times * ordered this product on 23/02/2015 and on 25/02/2015 at 19:00 clock already this got .... Conclusion: the nächser order only a toner shortly beforehand -> it works so well, "without reserve"
