i am totally interested in what BD has to say about all this. i would appreciate it.
Actually, my understanding is that needles that are too short may not penetrate sufficiently through your skin and enable the insulin to be injected into the body fat. If you penetrate to just below the skin, the insulin can pool below the skin and absorb improperly. I tried the nano and eventually moved back to the 8mm needles in order to get proper penetration.
I suppose it depends on how thick your skin is....:-)
This is the problem. Everyone seems to have heard something different or has a different understanding.
I am also most comfortable using the 8 mm needles for whatever reason.
4mm 32G Nano has been tested with adults with BMI 20 to BMI 49.

yes! yes! this is so great. thank you. my BMI is 20 with most of my junk in my trunk. the "no pinch" technique is why i thought the nano would be good. sounds much easier to bend around to shoot into the booty with a single hand.
thank you, JKD1, for the research links. This makes me feel safe to experiment.
I usually use my Nano needles 5-6 times before disposing. Never noticed it getting duller.
I always save the little cap from the needle, in my medicine cabinet, replace it on the needle when disposing and only after it is disposed of do I take out my new pen needle.
I also use an alcoho basedl rub, Germx, after washing my hands. This is the last thing I do after laying everthing out and just prior to picking my finger tip. I'm careful to avoid picking the same area. Sides of finger tips gives me more fresh areas of finger tip than if I picked the center of finger tip.
Sorry if all this sounds overly obvious.

I tried the nano's but they stung with anything over 7 units or so. I use the 5/16" 31 gage BD ultrafine needles.
