X4 LAB USERS + Others review

I like to cover a base on the x4 labs product.

it was my very first device and I paided a lot of money for it.
when I first used it I was using the silicone thick elastic rod.

it was not very comfortable and I got slippage and on to of that it hurt like hell when it slips out.
I tried the ( Head Swell ) and had the device on.
but then I got a cold head plus I knew there was a numb discomfortable due to lack of blood C

so I tired the plastic band strap. and did the normal way without and with the head swell.
the same thing had happened!.

so I tired some wrapping on the bottom of the penis head and put on the silicone rod but not to tight!
and also put on my plastic band to go over the silicone rod for extra firm grip.

this had worked for the slippage but still got the numb and cold head.
I don't believe this device is a very good device.

on low tension the head swell will disappear and to tight will make you numb.
so the only thing I would recommend is for a suction cup x4 lab version.

I believe there are a few out there and from what I have experienced the hard plastic hurts where as the soft suction cup does not!

this is only my experience. please share your experience and share some thoughts on how to stop the pain and numbness.
