The interior of this retainer is unique in that it features a funnel like shape to direct your urine out of the retainer without needing to remove it to pee like most retainers and devices - no need for constant adjustments throughout the day.

Our retainers have a “frenulum groove.” This groove provides the extra space in that area for additional comfort.

Keeping your glans moist with urine or lotion is a proven way to help break down the thick layers of skin that have built up on your glans over the years from rubbing against your underwear and pants. The result of this skin break down can dramatically increase your sensitivity and pleasure after only a few weeks of use.

Be sure to remove the device and wash daily with antibacterial soap and water.

Stainless Steel Retainer Worth the Extra Money

From: Justin - Verified Purchase

I initially purchased the non stainless steel retainer. There are a few issues with the non stainless steel retainer. The biggest issue is that once you begin adding weights, the hole for the screw attachments becomes stripped over time. After about a month of weight training the screw hole was so badly damaged I could no longer add any attachments. So I could only use the device as a retainer without any weights. The second issue with the non stainless steel/ plastic retainer is cleaning difficulty. Even after numerous washing, the plastic retainer will retain an odor. This is why I spent the extra money and purchased the stainless steel retainer. So far I've had the stainless steel retainer about two weeks. Because it is metal, I strongly doubt the screw hole will become stripped like the plastic one. Also there is very little odor when using the stainless steel device and cleaning is so easy. Also guys, there is one trick I have learned as far as wearing the weights discretely under clothing. I wear a jockstrap with a pocket for a cup. I insert the weighted portion into the pocket of the jock strap. I keep the jockstrap pulled loosely an inch or so below my waist so there is still some downward tension being applied by the weights. The tension will be less than if the weights swung freely, but the benefit is that the weights are discreet and the device is harder to loose because it is in the pocket of the jockstrap. I have worked out in the gym without the weights coming off using this technique. I have also ordered some drop crotch/harem athletic pants to try and conceal the weights for a full swing option. If you wear anything else, there is definitely an abnormal looking bulge swinging in your pants. This would restrict you to wearing weights only at home.

I can’t say enough about this retainer, it has to be the best retainer on the market today. The quality is unmatched by anything else out there. If you are serious about foreskin restoration then this is the retainer you should be using. The fit is great and so comfortable that I quite often I sleep with it on. Yes it is pricy but you get what you pay for and that is the absolute best.
I highly recommend this retainer for anyone restoring their foreskin, spend the money you won’t be sorry.

Worth the investment.

Just upgraded to the stainless steal retainer. The plastic one is nice but this one is amazing! The little extra tug you get just by wearing it by itself feels great. Works very well with the addition of weights and stays on longer without having to adjust. I would highly recommend this retainer to anyone restoring their foreskin or just to get a little erotic tug through out the day.

Best Retainer you can buy

I’ve been looking for a retainer for awhile that was comfortable, durable, and didn’t make it obvious you had something odd in your pants. The stainless retainer does all of the above and then some.
It weights about 3oz (don’t let that fool you, it’s heavier than you think) I love the fact that you can attach weights to is for added stretch, and you don’t have to take it off when nature calls.

It’s pricey compared to other retainers, but you get what you pay for and this delivers, you won’t be disappointed.

Finally the perfect retainer!

I have been looking for a good retainer for over a year and FINALLY found the perfect one. This is measured to fit, it's comfortable, doesn't pinch, I can wear it all day and all night with no problems whatsoever. I would DEFINITELY recommend it to anyone who is looking to increase sensitivity or restore foresking. If I could give it a rating higher than 5 starts I would!! A++++
