We received the Tango about a year ago in a We-Vibe combo kit. The We-Vibe was the main reason for the purchase, but the Tango quickly became one of the wife's favorites.

This thing is super powerful! The wife really only uses low and the wave setting. Anything faster than that is too much for her. It's waterproof and has provided many hours of hot tub entertainment. :) The Tango charges quickly, about 90 minutes according to the manual. Battery life has never been an issue for us. The tango is still going strong when the wife is done. It's really quiet also. With teenagers in nearby bedrooms, the noise level of a toy is important to us. You can barely hear it, even on high. The wife really likes the wedge-shaped tip. It allows her to direct the vibrations to just the right spot.

The wife's biggest complaint is the single button for everything. Pressing the button once turns it on, repeated pressing cycles through the different settings, holding it down for a second or two turns it off.

She enjoys starting with the low setting, and then switching to the wave as she starts to orgasm. In order to do that, she has to count button pushes at a time when she's not always capable of counting. Kind of spoils the moment when you have to put that much thought into it. If I'm using it on her, then this isn't much of a problem. I just have to remember to push the button 4 times at the right time.

My biggest complaint is the charging system. The Tango charges quickly, but the way it charges is absolutely terrible. It connects to the USB charger via magnetic contacts. The least amount of movement can cause it to disconnect from the charger. We have a cord running into the back of the nightstand to allow for discreet charging, but there's no way of knowing if it is still charging after closing the drawer. So we end up charging it on the nightstand where we can see the charging light, but this creates a potentially embarrassing situation if we forget to put it away the next morning.
