I have tried the We-Vibe 2, the Lelo Tara and the We-Vibe 4. My opinion, after trying all of these:
1) Bear in mind that couples toys are like rabbit vibes, in the sense that they are designed as a one size fits all sex toy. Now, this could mean that I recommend one to you now, that works well for me, and it could end up that the clit portion of the vibe just completely misses your clit, due to the different body shapes and sizes. So, when it comes to reading reviews for couples toys, I would say to read as many as possible and get an overall opinion, but always remembering that body shapes are different and one persons love is another persons hate.
2) While on the subject of "one size fits all" try and think to yourself "Are you the kind of woman that NEEDS direct stimulation to a very particular area of your clitoris with a very particular level of pressure? if so...you are like me, and may discover that finding the "perfect" couples toy is a bit like finding a needle in a haystack, because once you insert these toys, they will tend to add their own level of pressure and stimulate the area they land on, and during sex, you cannot move the clit arm around very much at all. You can press it down though, for more pressure, but yes, if you absolutely need one very particular place on your clit to be rubbed, pressed or vibrated, I honestly would recommend getting a mind blowing bullet vibe instead. Yes you will have to hold it, but so will you have to press and hold the couples toy, if you discover it doesn't quite hit your spots, so....the bullet gives more control and accuracy
Anyway, moving on to my opinion on the three couples toys I have tried
We-Vibe 2:
Oh no! Not good at all. Now this toy is like marmite and it really seemed that some loved it and some hated it. I fell into the hate pile. It slipped out constantly if you let go of it and if your partner pulled out too far, it moved LIKE CRAZY during sex and the clit arm would bounce all over the shop, missing the clit most of the time as it liked to turn into my thigh area. Also, the vibrations were not mind blowing.
Lelo Tara:
Quite nice. This toy, with its wide clitoral stimulator, actually stayed on the clit during the whole session. Bonus 1. It also rotated, when his penis trapped the rotating arm inside me, Bonus 2. It is comfortable and overall hit the spots I was hoping it would hit, but Lelo vibes are not amazingly strong and so I had to be super aroused to orgasm from this, despite the fact it hit all the good spots.
We-Vibe 4
Just testing this at the moment and so far, so good, but also, not good. Okay, compared to the We-Vibe 2, the We-Vibe 4 is a HUGE improvement. It actually stays in (For the most part) and it stays EXACTLY where you place it on the clit, unlike the We-Vibe 2 that slipped and slid everywhere. Also, the vibrations on the We-Vibe 4 are stronger than the other 2 toys I mentioned above. Excellent....except...see, I am beginning to suspect I have quite a short pussy. The We-Vibe 4 makes me want to cry because it stays still, it feels good, the vibrations are strong enough for me to orgasm....but the freaking thing overshoots my clitoris and most of the pressure and vibrations are pressed at the veryyyyy top of my clitoral shaft, at the start of my pubic mound. I want to cry, because I can honestly tell this is a brilliant toy, but it doesn't fit me!
Anyway, if I was to recommend one, from the 3 I have tried, it would be the We-Vibe 4. (You just have to hope that these toys will fit your body) If this one fits your body, I can't see you being disappointed. I would say its my favourite, out of the three because the we-vibe 2 was just a disaster for me, the Lelo Tara was good, but not powerful enough to make me orgasm, the We-vibe 4? It stays in place, its comfy, it has good rumbly vibrations and seriously, if this toy fits your body, or you are the kind of woman who can orgasm from indirect stimulation, then this is the best of the bunch, imo. Another advantage to the We-Vibe 4....multiple patternsand speeds that can all be controlled by remote (The we-vibe 2 had to be button presses which were almost impossible when the toy is inside, and the Tara...well, you CANNOT turn off the rotating arm. If the vibes are on, the arm is rotating and thats it.)
Anyway, hope this helps a little. I have reviewed the We-Vibe 2 and the Lelo Tara on my blog and the We-Vibe 4 will be reviewed there in a few weeks. If you need any specific info about these toys, just ask x
