eBay mintex discs

[lolsteve]

So the MGs front discs need replacing since I can hear them grinding while driving so looking to replace them. Since they are the front I kinda wanted to spend a lil more and not get Eicher rubbish from ECP. Since they have a massive sale on I went to look at the pagid ones and it came up as £37, great I thought! until it reminded me that was for one disk instead coming to £75 without pads
Out of curiosity I checked eGay and came across a pair of Mintex disks for £54.79

I hear people say good things about mintex but can I trust this do you think? Is mintex just a word slapped on to sound good but they'll just be some cheapy Chinese ones that warp instantly
