My partner and love everything about this product.
Awesome product , super fun and naughty to use via the app, the more risque the location the better.
Top Quality - just doesn't deliver.
I am only commenting on the sync as don't have the tango (which apparently is very good). We bought this to use together as seemed a fun idea. Out of the box the quality is obvious with a firm weight and A well thought out charging case. The vibrations are good but from there the practical function as a couple toy is nil.
Despite the clever double hinge it falls out if not lying down. It doesn't sit firmly unless your partner is on top or with very firm underwear. When on top, even though we are both slim the wireless connection cuts out. The function button is easily pressed when together which gets awkward. The app is cool but hopeless at remaining connected when used as a couple. Often you end up with it buzzing uncontrollably until something reconnects. A bit of a mood killer.
For the money we are disappointed, it isn't really a great couples toy as advertised and remains mostly in the cupboard. There is a new version which is supposed to be better, but nervous about risking money on it.
