So, I bought the Tenga Flip Zero EV in October 2019. By mid-May 2020 it broke. By broken, I mean that the two vibrating eggs somehow became intermittently functional. If I had my member in the EV, the eggs would partially vibrate, depending on how deeply I had thrust into it. If I pulled out, they would stop prematurely and not provide the vibration on way of pulling out.
I contacted Tenga and their support on 5/28/2020, and they asked me some questions and were nice and decided to send me a replacement . Shortly after June 3rd, when they shipped the replacement, I thought I was good to go. It lasted for some time, but then, around end-October 2020 the same thing started happening. This time with only with one of the vibrating eggs.
Either I use my EV waaaaaay to much, or the wire connectors of the eggs just don't handle the motions, or suction aspect, very well long-term and just break. I wish I could say it was my size... but I'm just average, all around. xD
So, the EV has become partially workable now, similarly to the first one I had. But, I've decided to not get another, or pursue a replacement. I feel it's a great concept, but they aren't necessarily very well made, and break easily and I would hate to break another one.
