They are what they are! made in China and cheap, sadly as in all things you get what you pay for, but like most things on E Bay, will anyone be there if they go wrong in 6 months, or do you accept that because they were cheap. The choice is yours.
My friend has just bought a pair of theser and i was really dubious at first coz i love my liverymans, but they clipped my cob really well... i do have to say though that i found them very heavy and wide to hold, i had sore forearms the day after using them and a very achy arm whilst clipping. I don't know about the durability though as his are new.
