Not necessarily the most important point but probably the first thing that any of us look at, this is how they compare:

Size Genetics has three packages in the range, all contain the same fully approved type one medical device with a varying amount of accessories and bonus items. prices start at £127.97 and rising to £ 249.50 for the Top of the range ultimate system

X4 Labs Has four packages in the range, the actual device will also vary depending on which package you buy.

Prices range from £57.77 to £254.50 for their premium extender

Winner – X4 Labs (for their entry level model)


The time spent wearing the device is crucial to achieve maximum gains, quite simply the longer that you wear the device each day, the faster and better the gains will be. To achieve the best results, comfort is crucial, too many inferior devices simply rely on a simple silicone loop to secure the head of the penis, something that can become painful quite quickly, limiting the amount of time that you can use the device.
