Yup I have tried a couple. The 2 I have right now are Stamina training unit (STU Lady) and Eva Lovia Butt which is my favorite one as its not too intense so you can last/enjoy longer. I like using mine and feel like it's much better experience than regular jerking off with a hand. But as some others have mentioned, the cleanup is a bit time consuming. I also have a fleshlight launch which is a game changer I believe. Automatic thrusting and it can get real intense.
The subreddit for fleshlight is really helpful with people's reviews, experiences and advice.
Edit to add: I don't think it is anywhere close to what a real vagina would feel like (sometimes its too intense and unrealistic) but it is way better than just hands
