Clever Choice ComfortEZ Insulin Pen Needles 31G 6mm 100/bx

Fast delivery, excellent product. I consider these just the right length for my sub-cutaneous injections of insulin. They work on most if not all types of insulin pens. My doctor wrote me an RX for 4mm, which were too short for me, then for 8mm, which I found overly long. I decided to just look online for 6m to see what my price options would be compared to an RX, and this price is better! These are just the right length, well packaged, and easy to use. Thanks for offering this! Great seller I'll use again!!

Waste of money. Really tight you have to push it really hard if you want to use it on HUMALOG OR LANTUS . twisting it hard trying to take it off is hard . And most of the time the Insulin doesn't come out it gets stuck somehow , i made sure to that its working like 2 units is coming out smoothly but after you inject it the insulin doesn't comes out it happened couple of times i inject it and the BG reading are interesting he sky. Don't waste your money

these are/ were the worst pen needles i've purchased. the sizing of the molds that make the threads is off. they are too tight to thread on and i've had to throw out two that failed to pass the medicine thru. Terrible, just terrible.

These needles work great with insulin pens.

Product exactly what I needed. Fits my Novolog pen perfectly and much cheaper than the brand names. Quality was excellent!!
