- It is lightweight and absorbs quickly.

Each 20mL bottle gives a concentrated formula with a high amount of niacinamide. The serum has a light, refreshing feel that goes into the skin quickly. It does not leave a greasy feel, making it easy to put on other products or makeup afterward. The serum works on things like bumpy skin, oil, and pores.
The COSRX Niacinamide Serum has ingredients like N-Acetylglucosamine (NAG), which helps to even out skin tone. It also has Zinc PCA, which helps with inflammation. Allantoin helps to make the skin feel better. The product is suitable for all skin types, but it is especially helpful for skin that gets oily and has breakouts. You can use it in the morning or evening. If you use it in the morning, be sure to also use a sunscreen with SPF 30 or higher.

It is heavy
Size: 58.3mm, Color: Black
Item was as described and shipped promptly. It is heavy and works well with my portafilter. I haven't had it long enough to really evaluate how helpful it is.

Great little temper
Size: 53mm, Color: Silver
Works great! Only problem is that it doesn’t have that feel of tamping. Wish I had more feedback. It just goes down very easily and doesn’t have that feeling of solid tamping. Now that doesn’t mean it’s not doing its job. Works fine but would like some manual feedback.

Take the guess work out of the flow!
Size: 58.3mm, Color: Black
I got this because when my wife makes espresso, it's watery. When i make it, it's fine. We needed a controlled Tampering method so we both do the same job.
This is heavy, and being able to use the whole hand instead of fingers, not much effort is needed.
Since we purchased this, we were able to make consistent espresso shots for sure.
