To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
Over half the needle tips took longer than 10 seconds to actually get the insulin out of the needle tube. About 25% of the caps didn't take the pen tip off the actual pen after usage. Got stabbed twice so far trying to take off the cap cause the needle stabbed through the side.
I HAVE BEEN TRYING ALL BRANDS AS WELL AS ALL SIZING..SO FAR TODAYS DELIVERY OF 31/6 DIABETIC PEN NEEDLES IS WORKING THE BEST OF THE LOT...THIN AND JUST THE RIGHT LENGTH...NO SENSE IN GIVING YOU THE GORRY DETAILS...INSULIN-TAKING DIABETICS KNOW WHAT I AM TALKING ABOUT
The ones I got work fine. I don't know what the issue was with the person who said they stabbed themselves multiple times and there was a flow issue. They have hard caps just like the expensive ones. I bought the 31x5 and the only issue I have had was sometimes a cap would be a little loose trying to install or remove a needle, but it didn't affect the usability or function and I just squeezed a little harder and it went on/came off. Compared to the price I paid for the "name brand"...$45/100... these were/are fantastic. I would definitely buy again.
Very good product at a good price. Most brands of needles I have purchased occasionally have a dull needle in the box, but I am half way through the box and these are good quality. I will definitely buy again.
