Can you please be more specific? We-Vibe is the name of a company (technically a branch of a company I think), or rather was, as We-Vibe merged with Womanizer to form WOW Tech Group.
Do you mean one of the C-shaped vibrators that is inserted into the vagina for PIV and stays in place during thrusting? That might be better termed a couples vibrator (see link here for several options), and several companies make them. One might best imagine them as a version of a rabbit vibe that is hands free and intended for use during PIV.
So if you’re just talking about We-Vibe products in general, we are huge fans of their products, which are really high quality. Our go-to vibrator is the We-Vibe Touch, which is kind of like a large bullet vibe, and we use it concurrently with PIV pretty much every time we have intercourse.
But if you’re talking about the C-shaped couples vibrators, that’s a more complicated answer. We got the We-Vibe Chorus a little less than two months ago, have used it 5 times, and have had mixed results. The vibe actually does stay in place and provides pleasurable stimulation, so it works as advertised. However, we have not successfully used it and it alone to bring Zelda to O. I think the difficulty there is that Zelda’s most pleasurable spots are not where the Chorus hits (it is centered right on the clitoris, but she gets a lot of pleasure off to one side). We did successfully get around that by using a 2nd clitoral vibe at the same time, but they don’t always play nicely together. Interestingly, she doesn’t even really “feel” the internal vibrations from the Chorus much, but they definitely have an effect by promoting blood flow there or something because sessions where we’ve used the Chorus end with her having a blended O that is shifted to greater internal contributions than she typically has, which is a good thing typically.
As far as PIV with it, make sure to use lube (which the instructions say to do). For me, it makes her feel artificially tighter, though the vibe is harder than the normal skin-on-skin sensation, so it’s not quite what you would expect. For her, she really liked the “full” feeling it gave, as it’s effectively adding to my girth, but only at the vaginal entrance.
The one place where the Chorus really shines for us is during foreplay. She can put the Chorus in place on a medium intensity and just leave it there while we talk/kiss/stroke/etc until we’re ready for PIV. The hands-free vibrations are great for getting her “warmed up” during that time. I honestly see that as where we will end up using it the most, but we’re going to continue trying new things with it, as the device really has a lot of versatility.
The We Vibe we have has “We Vibe II” on it, but it looks similar to the We Vibe Match (https://marrieddance.com/shop/vibrators/couples-vibrators/we-vibe-match/). In our experience, I would say it hasn’t been worth our money, but my husband has been wanting to try it again, because we haven’t used it for a long while.
I think with vibes it is SO individual. We bought a we-vibe, and honestly I don’t like it. I have found there is a specific type of vibe. We tried a Satisfyer, and I didn’t care for that either. But, I’m positive some women probably get amazing Os from it. It is just a process of trying them. The issue of course with the we-vibe is it is pricey. For that reason, I’m going to wait awhile and try it again. My favorite vibe was like $16….
You said in your comment that you’re interested in getting a “mutual climax”. You certainly don’t need this toy to improve your odds of getting that. Unless missionary (which for some people is a position where they can’t get a vibe on her clitoris) is the only position that your DW finds pleasurable, you can use a standard clitoral vibe simultaneous with PIV to go for a mutual climax. Any vibe with a strength close to what your wife wants should work in rear-entry or side-of-the-bed positions. Smaller vibes can work for woman on top (WOT) for many couples too.
