I started buying this model decades ago and have continued to replace it. They last FOREVER with moderate use so I have probably bought 2 over the past 25 years.  I have 2c/3a curly hair and this diffuser is a MUST for me.  It works great if I decide to blow it out too.  Looking forward to the model up grade on my next purchase :). Thanks CONAIR for a solid product at a budget-friendly price!
