Excellent quality, long shelf life, peace of mind as far as inconspicuous goes, and best part of all its very very cheap when bought in bulk from the right supplier. Plus the fact all sachets ive had (around 30 of them) were all overfilled by about 1ml, all in all i saved roughly %40 when compared to buying the average priced 10ml bottles. So if you dont mind sacrificing convenience to save $ you will be very happy with Stealth.
