The 'OZ' Band from Pos-T-Vac | Set of 2 Bands


Product Description

Pos-T-Vac 'OZ' bands offer a classic design and durable construction. The internal surface of this penis tension band features two knobs that apply pressure to the upper veins of the penis, helping the user hold a firm erection. The urethral notch on the lower portion of the ring allows space for ease of climax, reducing any blockage during release.  

'OZ' Bands are available in two different levels of tension, standard and high. The standard tension bands (yellow) are flexible, providing increased comfort and loading. The high tension bands (pink) are made of a firmer material for greater constriction and a strong hold.

    Did not hold erection

  2. Works Great 5 Star Review

    Very important to get the right size. If they are to small it will cause discomfort and not allow ejaculation. You need to make sure the ring is put on properly, larger grove at the bottom. I had no problem placing ring on tube and sliding off onto penis, just make sure you have adequate lube on tube.
    When finished make sure you rotate handles on ring to vertical position for easier removal. Also its a good idea to trim pubic hair before using.

  3. Confident 5 Star Review

    Posted by on 16th Aug 2018

    This has been a small eye opener for me. I am 47 and I have had some occasions of ED and PE. I discovered these wonderful bands (I do not use them with the pump) and purchased the large standard tension ones. They made my erection fuller. I had a great experience with theses and my wife noticed the fullness. Very easy to put them on without much of a hassle. The fit was comfortable as well but I could still have a problem with losing the erection. I decided to purchase the large high tension ones. I was excited to see how these rings would help me manage my PE and ED.
    When they came in the mail (very quick shipping I might add) I was so excited. As part of this order I also purchased the Stay Firm Kit by PosTVac for ED and PE | Penis Pump Accessories to place the new rings. (I will review this as well)
    I wanted to get use to the loading the rings before I would use them with my wife. The process is very easy as described in the instructions of the kit. As I placed the rings I could tell the control was greater and I could feel the base of my shaft begin to get firm right away. I adjusted the ring a bit and soon had a very confident result without a pump. I could maintain a firm erection even with purposeful distraction. The fit was tighter of course but not torture as some describe. I accepted the trade off of what this could do for my love life. I would strongly recommend either shaving your area or trimming the area closely as hairs will get caught with placement and removal. During orgasm this ring did allow a very small dribble of ejaculate to pass. I am okay with the retrograde ejaculation. Removal was required a little lube on the shaft to remove as the tension is higher.
    The performance of the ring with my wife the next time we made love was easy. I just stepped away placed the ring and came back. I was ready in a matter of seconds. Very natural feeling and my wife did notice I was fuller in size. I felt very confident but in my excitement of trying this out had to keep pausing to prevent PE. The sensations were heightened for a tighter experience inside my wife. My orgasm was a little different since I did not expel much ejaculate into my wife and my wife commented on this. We don't use protection and cannot get pregnant. The overall experience was good as I could have keep going with the control the ring was providing. I had the same experience the next night but after stopping a few times I orgasmed before my wife. I was pleased that my erection would be firm enough to continue until my wife orgasmed. It confirmed that this was my size! I was still firm but I didn't want to go past the recommended 30 minute wear so we stopped. removal was quick and easy. No bruising or soreness from use either! I hope guys that read my review will stop putting this purchase off. It is something that can change your love life and give you the flexibility of not dealing with meds. I so am excited to share my experience. This ring also helped the nice morning erection the night after as well. I am very happy with these!

  4. New experience 5 Star Review

    Posted by on 14th Apr 2018

    I looked at this site and seen it very informative. I am 46 and I have lost my erection a couple of occasions after I was engaged in intercourse with my wife. I would just pleasure her in another way and I simply could not orgasm since I was not erect. She would ask if she had done something wrong or if I was still attracted to her (weight). So there was a bit more pressure on me to have a working erection. This seemed to happen about three times in a row with semi erection or solid erection going soft. I was looking at some vacuum pumps and came across this site and the OZsupport rings.
    I purchased these rings in two different sizes, large and small. I am healthy and do not have HBP or diabetes. I did not want to take meds due to the side effects and I am able to get and maintain an erection 90% of the time. The medium was too small. I resorted to the large. I picked the OZ because of the notch at the bottom to allow me to ejaculate. I was preparing to have intercourse and I reached down and slipped the ring on. I had a firm erection but just wanted to see how it would feel, I was actually excited to try this. I hadn't shown my wife the ring so she asked what it was I showed it in place. I told her what it was she said it does not make me less of a man if I needed a little help. The ring made my erection even more solid and caused her to orgasm a bit sooner due to me being fuller. I was able to have unrestricted intercourse and was able to orgasm with a different sensation. The ring did restrict me ejaculating into my wife with the same volume. The orgasm itself was the same though. This support was wonderful as it is another tool to spice up our sexual encounters and offer true erection support. I think I will use this only when needed or special times. I don't think I would choose meds over this ring. This is a great product and men should look at this as a first line to help with an erection while doing some of the methods discussed in the blogs on this site.

  5. A nice surprise 5 Star Review

    Posted by on 12th Apr 2018

    I purchased these rings for a little fuller erection. I don't generally have problems with maintaining an erection but had a couple of times where these would have been great. I purchased the large and medium. The medium is way too small. My wife and I were about to engage in intercourse when I slipped the support ring on. I did not tell her beforehand (a little embarrassed) but I did say it will help with my erections. Pertty easy to put on since I maintain little pubic hair. As we began she noticed a fuller erection and pronounced veins. It was not in the way at any time and we could focus on one another. It was not painful but I could tell the support ring was doing its job. The combination resulted in her having an orgasm sooner than normal. The tighter feeling inside of her, allowed a nice response for me and orgasm as well. I could feel some ejaculate get past the support ring (we use no protection at all) with the majority oozing out once the ring was removed. My wife was very supportive of this support ring and remarked that it does not make me less of a man to use this. We enjoy one another when get together! Men go ahead and buy these, make a difference in your intimate times. I did.

  6. not very happy 2 Star Review

    Pro duct does not help with ejaculations as stated.

  7. Use for partial erections 5 Star Review

    Posted by on 15th Jan 2018

    Not stretchable for use with vacuum therapy device, use if you are able to get partial erection or full erection and want to maintain it. The bands will increase hardness of erection, allows me to maintain the erection and allows an ejaculate release. They are comfortable to wear especially tge medium tension bands.

  8. I ordered the wrong size 2 Star Review

    Posted by on 7th Dec 2017

    I ordered the wrong size and tension for my tube, the first one snapped before I could use it, the back-up one was too tight. Christian at customer service helped me get the right ones and sent me a label to return the damaged ones at no charge. Great customer service.

  9. easy on-easy off 5 Star Review

    Posted by on 16th Nov 2017

    it’s nice to try a product that works as advertised. easy to slide off the sleeve but i recommend a little extra lube so no hang ups. works better than the round ones that came with the pump. grips on the side are big enough to grip even with arthritis. Slides off with no discomfort. i’m on my 4th one (they are rated for 30 uses) with no failures.
