I love this shaver. I have used several different types, and this is definately the best for size, shape, and effectiness. I have not found it to be more or less flimsy than any other brand I have used. The little round, domed head fits well with all of the curves on a female body, which I have not found to be the case with any other shaver.
I have pale, translucent, skin with dark hair. Typically, even after shaving, the dark hair still shows through my skin. This shaver shaves so close that I don't get that ugly effect, yet I still don't get ingrown hairs. It's like magic.
However, I have noticed that where hair is growing at an angle that lays flatter to the body, and is a bit longer than it should be, the shaver is not as effective and I have to go over and over, sometimes pressing lightly and flicking the shaver against the hair growth to get all of the hairs. Luckily, I don't have a lot of hairs with this growth pattern, but I can imagine that, for those who do, this would be very frustrating. The key is that the hair to be shaved (any hair, growing against the skin or not) needs to be very short- the shaver doesn't work at all if that is not the case. There is no short cut for this step - it makes the difference between complete success and total failure.
Unless your hair is super soft and fine, or growing flat against the skin, this shaver will be the best shaver you have ever used. Follow the instructions, and you will love this little gadget.
