I LOVE this, I've been using it for over a year now. There are some small flaws, but somehow it has held up from a lot of use. At first I found this very difficult to keep in, so it took a lot of practice, but now it's easy and I can keep it in for a few hours if I want. I enjoyed the process of getting used to this gag. I'm so used to it now, I want a longer one. It's the perfect thickness- it allows airflow from your nasal canal into your lungs which is the most important thing for safety. As long as it's this thickness it doesn't really matter how long it is. The flexibility is good, some rigidity which is fun, but flexible enough to not damage the throat. I love the fact it locks, but I probably wouldn't allow someone else the control over locking it due to the safety risk with choking. I do use the locking feature a lot when on my own. For the price, I totally recommend this. There are some flaws. The first one I noticed is that I couldn't help but bite into it. Since having it for a week it got permanent bite marks in it. I was worried that one day I'd bite it clean off, but as I said it's been over a year with intense use and it's still sturdy despite the bite indents, so I no longer have any worries about that. One annoying (but not deal-breaking) factor is that the one I got has an ever so slight tilt to the right. The only problems this causes are that aesthetically, it looks just ever so slightly off centre when being worn. The other factor here is that it tends to slip to one side of my throat. This doesn't cause any discomfort, I just think I'd enjoy the feeling more if it was central. The only other problem which has only emerged with heavy use, is that due to a lot of saliva (saliva warning), the pink coating just around the base of the dildo has started to peel. That being said, considering this cost me £10 and I use it incredibly often, and have been for quite a while now, this has been WELL worth it. I think that is evidenced by the fact I want a bigger one. I was also a little put off by the hot pink at first, but I quite like it now—I think it's fun. I highly recommend this, it deserves more reviews, and I wish more products like this existed! Only buy this if you are fine with saliva and you enjoy choking!
