I am writing this review in exchange for receiving a sample of the purex crystals. Unfortunately, I cannot provide a good review on this product. First of all, I received the oh so chic limited edition fragrance and I am glad it is limited! It is very flowery and if I smelled it at the store I would never buy it. However, I do not like flowery scents in any brand so I'm sure I would like other scents better. Secondly, the crystals stick together and form clumps so you have to beat the bottle against the washer to break them up so you can pour. This was on a newly opened bottle so it did not have any chance to get outside moisture in. Very annoying and I definitely did not have this problem with the other brand of scent boosters I have tried. Lastly, and most importantly, although I used an entire cap full on the 3 different loads I tested this on, once the clothes went through the dryer I could not detect the scent anymore. While the clothes were washing I could smell it very strongly in the laundry room so I was surprised that it disappeared by the time they were done. I will not be buying this item!
