> 3 dayThis protector worked well to keep our mattress dry during an accident our 3 year old son had in the bed. Its soft to the touch, seems well constructed, and kept the mattress dry. I would highly recommend this product.

> 3 daySo far we really like this polish. It does have acetate in it, and smell like nail polish to a lesser degree, but it does, but with all the other things taken out of it, I feel better using this product.

Greater than one weekOmg I was using affirm relaxer, which started making my hair shed. So I figured Id go back to dr. miracles. My hair is starting to grow back. Dr. miracles is great on my hair. Now I will continue using it. I suggest you buy this if you have African American hair.

14-11-2024I have been using Trimedica MSM Powder for more than 8 years. Started using it because someone told me it would help with asthma. It is awesome. I drink it in distilled water. It is bitter, but I dont care because it works! I have tried the capsules but they dont work as well.

> 3 dayOutstanding, I got a custom configuration at a competitive price. This computer crushes a every game Ive thrown at it. The SSHD boots in ~12 seconds. This laptop can replace all but the very best desktops out there.

> 3 dayI love this oil. It has a wonderful scent that last just about all day on me. Its not oily, or greasy which makes it a plus for me. The price was very cheap considering the scent is very high! I definitely will purchase this oil again. I love this stuff!!

Greater than one weekI bought this because I need a flat iron that would work in Europe and it worked just fine. I continued to use it when I returned to the States - its a great product and I recommend it.
The NF-A8 is a highly optimised, premium quality quiet 80mm fan. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 2200 to 1750rpm. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

|
|---|---|---|---|
Flow Acceleration ChannelsThe NF-A8 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 bearingThe NF-A8 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
Scope of delivery
|
Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency.
