The extreme is still new and has gone through updates since it came on the market(faulty heat sensor placement)... its still untested as far as durability.

I bought my first volcano from ebay used for $350... I have used it daily (left on 12-15 hrs a day) for over 5 years and it still works great.

After you have owned and used the extreme for 5 years and its still working great come talk to me

Hopefully that company/manufacturer will still be around in 5 years... I know storz-bickel will be:thumbsup:
