I inject manually now too but used to use the autoinjector which is easy to use
and you dont even see the needle.
Rebif has a similar device. The needle is so small, I rarely even feel it breaking the skin, it is whats inside that takes a bit of getting used to. The Copaxone gave me a stinging - burning sensation for a while till my body adjusted to it, as well as site reactions, but I rarely get these anymore.
