I had previously used the Dr. Pen Ultima N2 with great results and this Ultima M8 doesn't disappoint. The M8 has a premium build and quality feel to it. The rounded body is comfortable to grip. The adjustment barrel has a gradual, tactile feel to it and a range from 0 to 2.5 mm to finetune. The 6 speed selection is handy for different parts of the face. It runs smoothly and quietly as well.

The derma pen uses a bayonet mount system for the microneedle cartridges. It is sturdy and easy to use. A total of 8 cartridges are provided: one pair for each of the 4 different pin-counts. They come individually sealed in sterile packages. They are quality cartridges as expected.

The pen comes with a charging cable and a USB power adapter. It also comes with a sturdy, plastic case with a clear top lid for organizing the pen, charging cable and power adapter plus any unused cartridges. A fabric sleeve bag is provided for the pen as well.

Overall, I'm really pleased with this Ultima M8 starter kit. It comes with everything you need to get started including 8 cartridges in different pin-counts. The pen is sturdy and solidly built. It is easy to hold and works great. Very good precision as well. I would recommend it. Good product.
