I was a bit skeptical going in because I personally never cared much for toys that offered internal vibrations but got this as a gift and gave it a shot. Aside from being super cute and soft, I love that it's discreet in both shape/ size and loudness (or lack, thereof), so you could technically easily wear it under your clothing if you wanted to.... I think the size of the main part is just PERFECT, and the little stem that has the on/ off button also vibrates which is... ideal. The vibration strengths are good as well-- the range is perfect for me personally, and even the strongest one was barely audible. The fact that you can control it via your phone is also wild to me-- I know that's not a new concept necessarily but I've never had a toy like that before so this was new to me! It was very cool to check out the pre-made patterns available as well as that you can create and save your own. And syncing it to music?! I gave that feature a try and it was pretty solid. Having the ability to manually change the vibration on the toy itself is also great. The long-distance control feature also seems neat and fun, I love the idea of that and that it opens the door for intimacy even when you're not physically with your partner. It also is shaped and sized in a way that allows for additional penetration with it already inserted, though I am sure that will differ from person to person on whether or not that is possible and/ or desired. Super cool overall, seriously, this toy is AWESOME. I really love it and I've only had it for two days but I'm already a big fan. And while it is a bit pricey, it's so worth it. I can't speak on the battery life or long-term durability yet but after using it for a total of 15-20 min, the battery barely went down. Get this!! You won't regret it!! Lol
