If you look at the orange sticker in the top corner of the box it says something like 'RC 4/12 certified carbon' does this tell the quality of the carbon?
I've only used 2 types in the past,my first was a Buddha which cost £17 and lasted no more than 6 months I then went Rhine Pro which seem to last 18 months. The 100mm Rhinos are about £40 the same as Phresh and the Red Scorpion in trying, in due to change my other rooms soon so looking forward to your thread.
Thanks for the advice bro gonna have to tickle u with some rep.
