    1. Not for beginners

      Reviewed: May 24, 2019 by AndySB, a Bisexual Married Male

      I wanted something with a bit of girth at the neck of the base and got it with this toy.

      As in my title, it's not for beginners and took a bit of warming up to be able to get it in so be warned.

      Once in you will feel the filled feeling and a lot of pressure on your prostate (if you are male obviously lol).

      The feeling of the air entering is a new sensation which is hard to describe but a good one.

      One tip I would recommend is if you have a wand, get an attachment that will fit in the tunnel and you'll be cumming and passing out in no time.

    1. Great product for beginners

      Reviewed: January 2, 2019 by Hoid1236, a Gay Going Steady Male

      Really well made product with a comfortable fit while you wear it.

      Made out of really good quality materials that make everything about this plug feel amazing.

      Comes nicely packaged and is the perfect size for taking away with you as it's nice and small so can fit in any bag.

    1. Open wide

      Reviewed: April 15, 2018 by Bear903, a Bisexual Engaged Male

      Expected nothing less of Doc Johnson.

      Well built plug, lightweight, looks good and most importantly feels great. Works really well with water based lube and extremely easy to clean. Is a good size. Took me a bit of time to get it in, but I haven't used many butt plugs before. Felt full once inside, which is an amazing feeling.

      With it being hollow, you can feel the air blowing inside you. Makes you feel exposed and vulnerable, which I love. Excited to try more with it but wish the hollow hole was wider. Felt sturdy once in, no risk of it falling in or coming out. I did take a picture of it in place and the view is amazing, but didn't think the site would appreciate the view. Easy to take out too. Love this toy and will be using it a lot more.

    1. A Kinky Plug for Butt Lovers

      Reviewed: November 25, 2017 by KingGrthy, a Straight Married Male

      I have been interested in tunnel plugs for a little while now. I have one other but it is still a little big. I was looking forward to receiving this because my experience with Doc Johnson, in general, has been very good.

      The plug doesn't disappoint. It is blemish free, and the silicone material is high-quality platinum grade according to the packaging. The 3D design and texture on the outside of the toy don't detract but it doesn't add anything either, in my experience it was not really noticeable in use.

      The first thing I noticed with this plug is how light it is, obviously being hollow means a lot less material.

      This isn't a huge toy but the hollow end can be a little difficult to insert without a warmup. After suitable preparation, I was able to get this in pretty easily and from there the user experience just gets better.

      Despite being hollow it maintains its shape really well, there is no risk of it collapsing and it is a good sized plug so really fills the space. Partly because it is light, and partly because the dimensions are well considered, it stays in very well, I did not have any issues with it falling or getting pushed out during solo play.

      The hollow core and lightweight create a really interesting sensation of emptiness and while it is difficult to pinpoint what exactly is different, it does feel different. It is a little too long to put your fingers all the way through but slender toys do fit.

      I had some post enema fun with it as well and if you are into watersports it is well worth getting for the opportunities it opens up,(pun intended haha). With it inside you have no control over what goes in and out.

      I also used some silicone lube with this toy and it was not difficult to clean and there was no noticeable effect on the material.

      Overall I really like this butt plug and it will get regular use for me, I would love to have a couple larger sizes to play with. This one is going to be best for intermediate to experienced players as it takes some working up-to to get this in.

    1. A new wow for me

      Reviewed: December 13, 2019 by Quizonmyface, a Straight Going Steady Male

      Saw a similar product but went for this one and boy I wasn’t disappointed. The package arrived and I couldn’t wait to put it to use. Having never used anything like this before, was a bit of a surprise when I finally got it in.

      Some anal relaxing lube was a must for this first timer, but once I got it in I was blown away by how great it felt inside. It looked great on a photo too, but can’t be putting that on here.

      So to summarise, anal relaxing lube is a must unless you're an expert. With these relax and enjoy the feeling, and the view is excellent!
