I had one of those... they are great, chemo is so much easier that way. You hardly feel the injections, it is feels more like someone presses on you chest.. it was preferable to a regular iv and of course they hit every single time.

It is not a big deal at all, it does not hurt to have it. I am not sure about hitting it howerever. Also, I tried not to have the seatbelt driectly on it.. just in case you actually need it (the belt). BTW when the time comes to take it out... this is done in 15 minutes and off you go.
