I just can't make up my mind about which of these two devices to buy. The Tesla looks great (even though i've heard people say it looks like a, errr, massage device) but i have seen bad reviews. On the other hand i like the look of the Vamo V3 too. I want a vv vw device so is there a difference between these two. Which is the better build ?. I don't mind having to use use two hands to adjust the tesla, because of the screen being below the buttons. I've also heard it's quite robust. What is your experience with either of these devices ?
