I love this Dr pen. It’s made of metal and is of high quality build. Feels good in the hand. So far I’ve used this pen 3 times and it’s worked flawlessly every time. Each time I’ve used the pen for about 20 to 30 minutes at a time and I’ve had zero issues with battery lasting. Pen comes with a nice protective case, along with three 36 pin and three 16 pin cartridges. The cartridges attach to the pen easily and the needles are sharp. (As a side note, if you are new to microneedling use the 36 pin cartridges first because they’ll penetrate your skin not as deeply due the increased surface tension that the 36 pins have against your skin in comparison the 16 pins. Thus the greater number of needles equals 🟰 more likely to bounce off the skin.) Another important factor is that this pen is authentic and comes with a verifiable QR code on the box that can be verified on the official dr pen website. This is important because when I was doing research on these pens I read that some of the other sellers sold counterfeit Dr pens. So it’s nice to know that this seller is legit and that you’re getting the real deal with them. The pen also comes with a two year warranty. Which I love to see that this seller stands behind their product. Overall, I’m super grateful for the folks over at Lifewit for selling a genuine product at a reasonable price that they stand behind with a warranty. Thank you.
