Not to use the new needles (NIPRO) that has been ordered for DaVita's patients at the Upland facilit

We feel the new needles (NIPRO) are not sharp enough to enter the skin without causing pain. Because more pressure is exalted it is more painful. It seems to leave more scar tissue after the needle is pulled out.
We will greatly appreciate if you let us keep the Medisystem's needles that we were using before. Yes, needles hurt when entering the skin but not as much pressure is needed as with the NIPRO's needles.
