Great product!

Wish I bought this stainless steel retainer sooner. It is very comfortable to wear and stays on even well climbing trees. I cant wear the weight while climbing cause it will interfere with my saddle, it is really easy to add after I get out of the tree. I highly recommend this product!

Fantastic upgrade!

I started out with the plastic version. I wanted to make sure that I was pleased with product: comfort, ease of use, that I would stick with it. Yes...so I upgraded to this more expensive metal version. I am SO damn happy with this upgrade. It IS very worth the price. As another review stated - the plastic version holds wonderfully but the metal version grips even better AND stays on with the added weights. With the plastic version it was possibly going to hold extra weights but with the metal - the grip is SO comfortable and strong I can add the additional weights. Plus as an added bonus - I am into BDSM play and enjoy eStim specifically to my cock and balls - this metal version conducts the eStim directly to the head of my cock. It is just a fantastic and wonderful upgrade for the price. Not often that you spend more and get so much more as well. The upgrade from plastic to metal is not just more money and a different base material.

If I could give 6 stars I would!

I wasn't sure if I wanted to invest in this stainless steel retainer so I first bought a plastic one and got used to that to make sure it was comfortable. I recently upgraded to this steel version and it's a fantastic investment! One initial concern was that since it is so smooth it wouldn't grip as well, but if anything it grips better than the plastic version. It's also super comfortable (not that the plastic one is at all uncomfortable) and the perfect amount of weight to maintain a nice gentle day-long tug.

So far, so good.

I bought the whole kit with the new gripper and stainless steel weight set. Works awesome with very little to no slippage. I’ve found that if you clean the retainer, gripper, and your shaft skin with alcohol, it will be better, and stay put.

Awesome product quality as usual !

Thanks very much for continuing your very excellent product quality. I highly recommend it to everyone. I have finally moved up to the stainless steel version of my retainer and packaged it with an 8oz stainless steel weight / set of grippers. The plastic was very good for my start when I was able to start with retaining after months of manual stretching and got what little of a foreskin remnant I was left with to have enough slack skin to accommodate retaining for the majority of the day. The stainless steel retainer is even more comfortable and the great added benefit is that the ~1.75oz weight of it keeps me in more of a gentle stretch for all of the time I have it on, no more taking it off during the day to do manual stretch reps, adding the 8oz weight during bathroom breaks is easy as well and very beneficial for progress, peeing is easy and quick just removing the bulge and I think thru the stainless steel is more comfortable than peeing naturally, not sure why maybe more even pressure or back pressure but I have always had slight pain urinating since childhood, probably I have always had a mild case of Meatal stenosis, the grippers are awesome as usual and I have had no issues with any disengagements, they fit very comfortably, I do use the strap to ensure no issues. Very happy as usual with SR and their products, cannot thank you enough ! Be Well !
