Wow, when the Lush 2 works, it's incredible, but I' have found that the most reliable thing about it is that it will fail to connect to the Bluetooth and my partner is likely to be disappointed. I've had the thing for about 4 months and it is very VERY rare to be able to use it without dropping connection to the app. Last night I was out with a lover and I connected the Lush to the app before giving it to my girl and having her insert it, and then return to our table. For the next 2 hours, we sat there hoping that we'd be able to enjoy it together. It went live for about 90 seconds, before losing connection again. We got 90 seconds of use out of 2 hours trying.  Pretty much every time I use it, the most reliable aspect of using it that it will lose connection, often and for a frustratingly long time.  About half the time I do get to enjoy it for more time than not, and the times when it works are amazing. I would never recommend a product with this level of reliability to anyone.
