I bought these to replace the old stylus's that were on my Ortofon cartridges since they were broken.
I've had them for a little while now and have even taken them with me at a few gigs and they've been holding up fairly well.
However, I have to point out that I don't feel that they are the best needles around, to be fair I still have to try other brands for a longer period of time before making a definite evaluation but if you need a quick replacement/fix stylus for your cartridge before a party or even for home then don't look any longer, this is it really.
Thomann (as usual) send everything at the speed of light and well packaged. Staff are always very helpful and effective, I have yet to have a real problem with any order I've made, everything has been practically perfect since I started using this website a few years back.
So yeah, there's not much left for me to say except to recommend these stylus's, they're the same thing you would find on the official Ortofon website really (they are even cheaper here if my memory serves) so don't hesitate and grab them from here whenever yours break down!
