I know it needs to be prepped but I've never tried it. Some people seem to think it's the best thing ever, some don't see any benefit over their previous substrate. I don't know anyone who had a bad experience with it. I don't like how their marketing is misleading personally. I'll just copy my response from an email when it got discussed.

I mean even a recent example, I'm sure on the reptile groups you have seen the coconut husk bedding repichip being advertised like heck as the latest and greatest thing. Well their advertising actually made me snub them as they tell lies when comparing it to cypress. http://www.reptichip.com/fans.html . Cypress absorbs oder, has great longevity as it can be spot cleaned, can be organic. So Wtf is up with the chart? You could truthfully claim cypress takes longer to grow and depending on who's logging it, has a negative impact on the environment. Why tell lies? Also their whole faq reads like stereotypical marketing, I can't stand it. The thing is it actually may be a better bedding, but their advertising made me say forget it. Unless there is some massive benefit I will never even try it.
