Comparing the CB's
Which one is right for you?
Buying your first CB?  We suggest you spend the extra money and purchase  the CB-6000.  
They fit 95% of men and are very comfortable and cannot be seen under your daily clothes.  
You get 5 rings and 4 spacer/locking pin combinations with the 6000, 3000 or Curve.

Special Features
Shaped most like the male
penis.  The tube is a bit
wider than it is thick and
the head is nicely
designed.  Small vent
holes on side.  Points
down more than the
others.  Connection flange
is not as tall as the other
for better concealing.  
Locking pin is shaped so
that the lock cannot twist
around while wearing.  
Very comfortable, easy to
wear.  Very durable and
well thought-out design.  
Easy to stay clean in for
long periods.
Tube is more round, nice
head design.  Vent holes
are on the top.  Very nice
CB, most popular in the
world up to now.  Very
durable.  Easy to stay clean
in for long periods of lock
up.
For the longer male.  Has
vent holes that go the
whole length.  Very
appealing design with its
long curve.
The cage is separate from
the back ring.  Very strong
silicone cage and ring.  
The rings are totally
round, unlike the
BirdLocked which is more
like an upside-down
triangle.  Some men find
the Bon-4 easier to put on
because of the ring being
separate from the cage.

Only comes in one length
for now.
The Birdlocked is made of a
nice soft, yet very durable
silicone.  It came on the
market in February 2009.  It
comes in a Short and a
Regular tube size.  Each
tube is permanently attached
to the back ring.

The BirdLocked comes in
different colors.  Also, there
is the Pico BirdLocked with
soft spikes on the inside of
the tube.

6000.

No CB is 100%
concealable.  There will

of "you" down there when

So-so.  The design is such
that the tube goes out a bit
further.

The Curve will have a bit
more show by its very
design.  It is more bulky
than the others.
Yes, the Bon-4 is as
concealable as the
CB-6000.  

However, no CB is 100%
concealable.  There will
always be a bit more of
"you" down there when

Yes, the BirdLocked
products are very
concealable under clothing.

But like the rest, there will
always be a bit more of
"you" down there when you

* The CB's can go through airport security with the regular lock or the plastic locks.
** The CB-6000, CB-3000, Bon 4 and BirdLockedcan be worn for jogging, swimming, karate, bike riding, climbing Mt. Everest,
bull fighting, NASCAR racing, or any other sport you might think of.  Because of the Curve's design, it can still be ok to wear
while active in sports or similar activities, but you might find it just a bit more inconvenient.
