We've only had it a short time so can't comment on everything, but so far we are very happy with this purchase. Contoured shape makes it very easy to handle. Cordless does not mean less powerful, it's every bit as powerful as our previous wand, but with a wide selection of speed and vibration patterns. There really is a setting for every mood or situation. Much cheaper than other similar wands. Cannot answer to battery life or overall durability since we haven't had it long enough and will update if need be.
