My experience with epilators so far.

[Thylacin]

So I just got my emjoi emagine last evening and tried it on my legs. It pulled a lot of very fine hairs out, but it also had a tendency to break a lot of hairs off (on either setting) and leave a lot of stubble that it couldn't then grab. Plus, it would entirely miss some hairs (no matter how often or which direction I went over them) that weren't even flat against the skin. Later, I clipped my armpit hair with electric clippers, then epilated. The pain wasn't nearly as bad as I would have thought considering what I had read, and my armpits are super smooth, yay, but it still did miss a few hairs.

Considering I wanted an epilator for my legs and arms, and it did very poorly on both, I am going to have to return it. I might get a Braun wet and dry kind instead, since that one is a little cheaper, has a light, and might work well enough anyway (and I'll see if I have issues with that one snapping hair rather than pulling it!).

They're not for everyone.I couldn't get on with it,it hurt and didn't do a very good  job.A friend reckons it's the greatest invention ever made!

I had a similar experience my first go with it on legs/arms. If you keep using it the hairs will eventually get pulled out and seem to become easier to remove the more you do it.

To get hairs that don't want to pull out, try moving the epilator side to side over the hair, it will get it

Btw, I have exactly the same epilator!

My main problem is having it break off hair at skin level. It did this a lot on my arm. There were a few hairs that I couldn't remove no matter how many times I went over them, how I pulled my skin, or which direction I moved the epilator (even side to side). That's not as big a deal as the broken off hair though. Here's a picture of my arm near the wrist for what I mean. The dark spots are hairs that broke off too short to try to re-use the epilator on (though I can still pluck them with tweezers). It's just a bummer that I'm getting so much stubble, since that's the point of not shaving . Maybe I'll have better luck with the Braun one. I guess this is definitely a case where YMMV!

So I just got the Braun Silk-epil 7 from amazon. Tried it a little bit on my arm and it seems to be working well. I'll give it a longer test later.
The tweezer head on the Braun seems to be engineered very differently then the Emjoi, so I think the difference between the "72 tweezers" on the emjoy, vs the 40 on the Braun might not be as significant as it seems. The Braun's instructions say to move the epilator slowly against the hair's growth, while the Emjoi's directions say to move the epilator quickly in short strokes in the direction of growth. So it would seem that they're both made to function differently.

I really like the pivoting head and light on the Braun model too. The light really makes it easier to see.

The braun is also quite a bit quieter, IMO.

Of course, I like a few things about it now, but I'll see when it comes to actually doing a whole leg

I got a chance to use the Braun on my legs and I have to say the braun seems far superior. Of course ymmv, but I had far less trouble getting all the hairs with the Braun, and it didn't seem to break any hair off. It was slightly more painful than the emjoi, but I am guessing that is because it was actually pulling more hair correctly with every pass. The light on it helps a lot too. Even though the Braun has less tweezers on the head, and sounds like the motor is less powerful, the design of the head seems to make a big difference.
The only downside is that the Braun must be unplugged to run (safety feature), which means the battery will eventually become unable to hold a charge.
