This classic "cheap chrome chastity device" seems to be everywhere on the inte under many different names. Though it looks intimidating, this chastity piece is "one size fits few" and not adjustable. In spite of those limitations it is often a submissive's first foray into metal chastity because it is so inexpensive. This device leaves a noticeable BULGE in the front of your trousers so I would not consider this to be a subtle or easily concealed device. It is heavy for its size and tends to pull on your balls when worn. However, some men find the heaviness to be a pleasurable side effect and others use a jock strap to take some of the weight. If you are within a narrow size range and want something ready-made for very little money, you could give this one a try.
