Is this device worth buying?
My experience with these type of scales using electrical current has not been too good. I don’t think they’re that accurate and can be way off sometimes as well (lots of variables involved such as level of hydration at the time of the reading among others).
I’d say its better to invest in a decent set of calipers and then take readings weekly which in time will make you better at it as well.

I’ve heard that they can vary by 5% or more based on hydration level. Unless you are always 100% hydrated, they aren’t worth much.
Do you mean that a someone who is actually 13 percent BF can read anywhere between 9 and 14% with this device, depending on his hydration at the moment?

Yes, and that’s assuming that the device is accurate in the first place. The device itself could measure you +/- a few points based on your specific fat distribution.
The idea is that it sends a signal from one hand through the body and out through the other hand. Muscle and bone transfer the signal quicker than fat. So in theory, the faster the signal moves, the lower your bodyfat. I believe that since some people carry more bodyfat in their legs or waist or upper body, the reading will be less accurate for some people.
Couple that, with the fact that dehydrated muscles transfer the signal at a slower rate than fully hydrated ones, and your readings don’t seem that much better than holding a shoe up and guessing.
