We have an older we-vibe product and love it but when we saw that the new we-vibe 4 plus not only had a new shape but came with a remote and options to use your phone as a remote we had to buy it. We found that it is very easy to connect with our iPhones (we have a iPhone4 and iPhone5). The app is really very easy to grasp for anyone used to using a smart phone. We noticed that we got each had bluetooth error messages, but then we realized that this happened as we were sat next to each other when testing out all the settings and controls on both phones, once we moved a reasonable distance apart this stopped, so it was the phones causing issues for each other. This is a great addition to intercourse and going solo it makes a great vibe. The surprise for us was when my husband suggested I wear it going out one night, under some panties it makes a fun remote control vibe. I find the vibe easy to insert and place correctly, and can wear standing or just pottering in the house, but when I wore it as we walked out to the bar. It may look like he is playing a game or sending a text to anyone else but my clit knows what he's doing! It was really fun and a bit kinky. Overall, this is a great product and we would highly recommend it!
