Never bought from them either so can't say personally.
They have some mixed reviews on Google, but they're big enough that should you have problems I imagine you would be able to get your money back without too much hassle. So I can't vouch for them, but personally I would be happy enough...
Brand new for R1500?

Please buy them all because the urge to get myself one is becoming unbearable.
