> 3 dayA fine masala dubba: sturdy construction, decent size(small enough to fit on a shelf), and has an inner cover. This is my first dubba, so I cant confirm the Superior Quality, but it does what I need it to do and I dont imagine any reason you might be disappointed with it. Ive heard that some cheaper ones arrive dented or the lids are warped, so maybe the superior quality is in the slightly thicker metal.

> 3 dayI bought this for my granddaughter. It has kept my weetheart very warm this winter. Its just as described and my daughter said it washes very well with little to nil shrinkage. True to size.

Greater than one weekFor a towel this was pricey, but worth the splurge. It is soft and thick, I was trying to avoid those really thin towels that dont absorb a thing. My daughter will love it for her bday.

> 3 dayI ordered the DermaVital Night Cream to use with my Derma Wand and it lets the wand glide easily. It leaves your skin feeling very smooth and you only need a little dab. It has a very clean and fresh smell and seems to melt right into your skin. I would order this product again when I need more.

> 3 dayAs always...Canon delivers. Ordered from Ritz through Amazon and everything arrived on time. Ritz sling bag may work for smaller scale cameras but surely not for the 5D. Bottom space just too small.
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.
