Metalab bits?

[HafDressage]

I've decided I want to switch from my curb with short shanks to a standard shank bit. He isn't picky about bits and so I think i like the look of the standard length better, so I'm going to switch.... this of course has led me into bit land, which has way too many options.

Before I buy another HS bit, I happened to come across this and thought it was interesting (and WAY cheaper):

Has anyone ever purchased a metalab bit and if so thoughts on it? Certainly a nice price range relative to the nearly $300 for the HS bit.

I have, I found they discolored quite a bit over time.

I have. Haven't had a problem
