Doc Johnson continues to raise the bar each year with innovations and produces many of the highest-quality and most well-designed products on the market. Driven by the principle that exploration of oneself and among consenting adults is a healthy and necessary part of the human experience. Each product produced under the Doc Johnson banner is created to cater to several interests and identities for endless custom options.

Male Review: It came in a box that I later used to ship a desktop computer in. : ) This thing is huge and long. When you use this, please make sure it is well lubed and your hole will thank you. It has a fair amount of "give" which is nice considering its 8.75" circumference. I just can't ever fit the whole thing inside though I have tried intently. Clean up is simple provided you have a waterproof sheet beneath you and a kitchen sink nearby. Last thing I would suggest is keep the plastic frame which comes with it otherwise the jelly it's made out of will pick up dust and lint. This thing is HUGE and LONG. Enjoy!

Absolutely amazing. First off this thing is massive. Definitely a once in a while kind of toy. It is soft and very slick with lube but form enough to insert. Definitely need a spouse to help when using this thing. I would say it gave her that full stretched feeling that sends orgasms to the moon and back. Possibly the best orgasm I've ever given my wife based on the moans and groans and flushed cheeks.

Now for those who haven't done anal before and are wanting to experiment, this toy is not for you.

Reason is, this thing is thick. And if your patient and want to have a huge orgasm, you need to practice before this. If done right, this toy will help you get off quick. My girlfriend and I are into anal so she got me this toy so we could both enjoy it at the same time. It was difficult at first sense I never tried something THIS big before. Other than that, this toy is amazing and has been perfect for me and my girlfriend.

Reviewed in the United States on November 14, 2017
I am definitely an aficionado of expanding my...abilities...in certain areas. (It should be noted I'm male.) I've been playing with large and VERY large toys for years now. When I saw this one, I got a little excited...until I received it.

This is touted as, "The Great American Challenge," but for me, there was no challenge at all. I bottomed out on it on the first run. This was disappointing. I was really hoping for more girth than this toy is able to provide. While I'm still working on depth and this helps in that area, I wish it gradually got a LOT thicker as it went to the base - and this toy simply doesn't.

If you're fairly new to the world of large and extra-large toys, this might be a challenge and pleasure for you. There's plenty of flex and give in it since it's jelly; it curves to your interior nicely without forcing its way through anything. It's nice and smooth so there's little risk of incurring bleeding. The head is nicely tapered for easy insertion, too. So if you're still working on taking XL toys, by all means get this one. If you're a pro (able to take 3.5" diameter toys and larger), you're probably not going to find this toy very useful except as a warm-up.

I found this guy online and searched him up on Amazon to purchase, which is why I rated him 5 stars (because my gripe has nothing to do with this seller), but I'm disappointed he doesn't meet the measurements he's supposed to be everywhere they're quoted, because that's the reason I spent as much as I did to buy him. Everywhere I found him, it quoted him as being 3" wide, but he's only 2.5" at most. For 2.5" I could have easily spent half of his price for another quality product, but there's not much in the 3" range.

Aside from that, he's very well made, almost no smell straight out of the package and what is there will easily wash away. I don't like is how heavy the base is, but that's easily enough fixed.

This is very flimsy and difficult to insert. It will not stand on its own and collapses very easily. It should be a little more rigid for ease of use. Don't bother buying it. Not worth it. They must have taken the picture when it was hung upside down so it looks like it stands on its own. False advertising.

Looking for a step up from my BAM Doc Johnson fat didlo, just was too awkward..weight was too hard to manage solo and if you are playin alone, you need to BE SURE you don’t have any lube on your pushing hand. I did like the diameter of the head and it took quite a bit of effort to get it in. The view once it was in was superb and I got a few good pics to share with dates. The diameter of the shaft was too small for me as I was looking for something thicker and closer to the diameter of the big, fat head. Pulling it out was also a challenge but the pop was nice. The smell did fill up the room but that may have gone away after washing a number of times. Functionally, 1/2-star. Head diameter and feel, 4-stars, weight, zero-stars (it’s too damn heavy) Shaft 2-stars. Ended up tossing this in the garbage can since my play time is limited and

Still a great challenge. One of my favourites. Its very soft and very smooth. Lots of fun for advanced users. Warm up and use lots of lube

2.0 out of 5 stars Si flette, si storce e ora si scioglie pure.
Reviewed in Italy on August 3, 2021
Dimensioni e forma soddisfacenti, troppo flessibile, difficile da inserire se non allenati. Una volta inserito si flette e non permette "il movimento". La base è troppo stretta e se non aiutati si rischia di farlo cadere di traverso. Sempre pulito e sterilizzato come da istruzioni dopo ogni utilizzo e conservato al riparo e separato da altri toys, dopo quasi un anno la superficie ha cominciato a sciogliersi. Prima volta che succede con un prodotto Doc Johnson. Spiacente ma non lo ricomprerei.
