I've been wanting one of these for years & I'm so glad I finally made the leap & purchased one. I spent some time looking through reviews, & came up with this one as being the best choice. I absolutely LOVE it! It has 4 settings, 1 - 4. 1 being the lowest & 4 being the highest. For me personally, the 1 setting isn't quite breezy enough. 2 is just perfect & 3 and 4 are very breezy! Of course the higher the setting, the louder the "hummmmm" of the device is, however I don't find it to be bothersome. In fact, I'm a sleep with the fan on all year long kind of person, so I find the humming noise of the fan to be quite peaceful. I ran it on speed 2 for 3 hours straight & it only dropped about 33% in charge. It feels very well made & sturdy. Not too heavy, in fact, after just a few minutes it felt like it wasnt even there. It fits my neck perfectly & doesnt feel like it is going to fall off. I even wore it the opposite way to get a little more air on the front part of my face, & it didnt fall off. It definitely cools the sides of your face & neck, but the actual front of the face still could use a little more of breeze. Aside from that small little sad part, I am definitely happy with my purchase & would certainly recommend this product to anyone looking for a little portable breeze, anywhere you go! : )
