I wasn't expecting much at this price point. I get high quality bits at work for free from the parts window, so I just wanted the index to be honest. When it wears out I will replace it with more expensive ones. The index works, but I've definitely seen better ones. The fact that the rows don't split at all is an embarrassment, but at this price point it's again a bargain with all the parts included. I've already used a few bits and changed a few things. It's fine for basic home use. However, I wouldn't count on them being used in a production environment all the time.
