*The Good:  All functions work; not too loud on Low; not too big; Hot setting isn't 'burning' hot; Concentrator attachment doesn't fall off while using. 
*The Not-So-Good:  
It took more time than expected to dry my damp shoulder-length fine, slightly wavy hair. 
Wish it had hi / med / low blower settings - high is loud, and blows my hair around too much  / low is too low to dry it quickly.  
Warm setting is lukewarm at best. 
The dryer feels ok in my hand but is relatively heavy for its size. 
It doesn't do much to tame my frizzies, with or without product applied.  
*Conclusion: This is no Dyson hair dryer, but at ~ 1/10 the cost, it does an OK job.  (I received this product at no cost to try, and to give my honest impressions.)
