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.
I tried these needles when my meds changed and I needed to inject more times than previously, so I needed more needles than I had. My prescription is for BD Ultra-Fine Mini Pen Needles, 5mm x 31g, so these are an exact match. At a cost of $16.99 for 200 needles versus $70 for 300 needles with my prescription, he math is simple. I was leery of product quality and the packaging of each needle is not quite the same quality as BD. The cover of the bottom of the needle is much thinner paper and it tends to curl but I have yet to find one that has lost its seal. The injection itself is as comfortable as the BD needles which was a very pleasant surprise.
And again, do the math: $17/200 versus $70/300. That means for the same price, I can get over 800 of the TRUEplus needles instead of 300 of the fancier BD needles. The needle quality appears to be the same so who cares if the needle containment isn't as fancy as long as the needles are still sterile and safe to use? I don't, especially since they are a use once and safely dispose of item. To quote the late Gene Siskel and Roger Ebert, "I give it two thumbs up."
Worked fine as a needle, but the female thread is not a good fit (compared to B-D) on Humalog and Tresiba insulin pens; a looser fit, a bit fiddly to get off. And the outer (conical) protective cap is not a secure “click” fit on the needle base; often comes off when removing the used needle, unecessarily re-exposing the needle. Manufacturer needs to tighten up tolerances !
I received one box of the four supposed to be shipped and after trying a handful of them, I don’t even want the other three boxes to ever show up. Needles clog with the first use. Hard to pierce the skin with them. I had to change three needles to get ONE DOSE. Crap product.
I'm not thrilled with these. Bottom line, they deliver insulin as required. But... While I sometimes get a nice pain free injection, about half the time it hurts pretty bad. That happens with all brand needles I've tried, but not as often as with these. Also, the plastic cap that covers the needle is tight enough out of the box, but when you use it to take the needle off the pen, it's not tight enough. I have to squeeze it pretty good to pick up the needle. And sometimes the needle still falls out. Not good if you don't notice it, and then step on the needle with a bare foot. The needles I've been using cost $11 for 100. These are $17 for 200. It's not enough savings for me to take the hassle. But if money is tight, and these are what you need, they do work.
