Review by Adam Griffin

EnlargementWorld.com chose to rank this device as #1,
so what's the deal? Well we landed on their homepage through a Google
search and began to inspect the site. There was quite a bit of
information on how the device works and a little result calculator. So
for the sake of fun, I thought I should try it out and see what it
would give as an estimate. They claimed 1.5 inches in 3 months which I
thought would never happen. The options to pay were C.O.D, bank
transfer, money order, MasterCard, and Visa. So on the expense account
of EnlargementWorld.com I ordered my X4 Extender
Deluxe Special Edition for $295.95 with free shipping and waited
patiently. Three days later UPS arrived at my door with a package. When
we received our X4 Extender Deluxe kit in the mail we
wanted to see how it would fare. After testing many of the major
companies products we wanted to test the lesser known brands. Was it
too good to be true, lower price, promises of better quality and
comfort?

EnlargementWorld.com was pleasantly surprised. The X4 Extender arrived in discreet packaging and was in sealed packets. As with several of the other extenders partial assembly was required. X4 Labs had an extender with something they call comfort strap technology.
It was the strap which would go through the support piece. Other
companies used rubber tubing, some would even dig into my upper thigh.
The comfort strap appeared to be the most comfortable of them all.

Three months down the line I seemed to be up to an
inch more in size and noticed I getting wider. Well, now I wanted to
add an extra piece so I could continue my 'treatment' and included in
my package was a bunch of various extensions. I had seen the other
products on the arrival to EnlargementWorld.com offices and none of
them had many upgrades. Although X4 Labs only had a instruction manual but they provided more than enough parts.

The Upgrade Kit

One option that is exclusively available from X4 Labs is the ability to update noose-based extenders to incorporate their Comfort Strap.
During our review we also ordered an upgrade kit to see their
compatibility with other products. What we found was that the upgrade
kit was fully compatible with all of the extenders on the market.

For those of you who have tried other extenders you're probably
aware of the un-comfort the rubber tubing can cause. This basically
allows you to update your device to a more comfortable version at an
extremely low cost. For $79.95 you can completely upgrade your extender
to incorporate all the benefits of the X4 Extender.
