    There are some important things to remember when judging Impossible films compared to the traditional Polaroid films you may be used to: this is NOT Polaroid film, nor does it pretend to be. None of the components to make original Polaroid film were possible to recreate or reproduce after Polaroid stopped making it and demolished the factories that made the original materials. This is a completely new film from completely new and evolving materials that are COMPATIBLE with classic Polaroid cameras. In about 1/3 of the time it took Polaroid to perfect and release the original SX-70 film and cameras, The Impossible Project has re-invented the process by which the classic integral Polaroid films functioned and has produced a very impressive product in pursuit of saving Polaroid-format analog instant film from extinction.

    Im 72 years old and this hot water bottle is a treasure. Ive been suffering residual nerve pain on one side of my face after a Bells Palsy attack, and while pain pills didnt seem to help, hot compresses brought instant relief. But it is a nuisance to soak a cloth in hot water, wring it out, and apply it to my face, only to have it cool off in a few minutes so that the process has to be repeated.

    For a toy like this - the main thing to rate it on is - did it make you cum. The answer is yes!

    I have owned this brush for just over two years and I am still very happy with it.

    Im never in one place for too long, due to military obligations. At first, I was a little shaky paying $2400 for a laptop. Being my first MSI laptop I wasnt sure what to expect. Upon arrival (which was pleasantly quick) I was happy to see that MSI did a fantastic job of packaging. It arrived without a scratch. Set up was decently quick. Once I got past all the initial set-up and adjusting the settings to my liking, I decided to give it a test. I downloaded a few of the newer games I knew would be demanding for a standard laptop. I was honestly shocked to see Fallout 4 (and many other games) run at maxed out settings. Its a whole different gaming experience I never thought Id see. No screen tearing, ultra settings, and the frame rate was fantastic. Honestly better than any previous computer Ive owned. If youre looking for a high end, beast of a gaming laptop. This is it. Look no further.

    After much research we went with this travel system for our son, weve been using it for almost 3 months and we absolutely LOVE IT. We did have an issue where we received the same back wheels for the L & R sides, they need to be different in order for the breaking mechanism to slide on properly, but after a REAL quick call to baby trend they sent us a brand new wheel so it worked out just fine....The one thing I LOVE about the infant seat is that it has an adjustment wheel on the back so you can simply turn it to move the straps/headrest part up and down, no hard pulling the straps through then re-looping them to a higher/lower setting. The stroller is super easy fold and open after some practice. GREAT travel system for the money for sure!!...This travel system was made in 2008, and it is new enough to have that latch mechanism for the cars so it is difficult to adjust with an older vehicle, we had to prop the base up with something so that the baby was reclined at the correct position. Thats the other thing, this seat has little holes on the side that indicate whether or not the seat is properly reclined on flat ground.

    Ive tried a ton of various teethers, and these hand and foot ones are the only ones my child seems to like! Hell spit out the others or stop gnawing at them after a few seconds, but these will actually seem to satiate him for quite awhile. He seems to prefer when they are frozen to refrigerated, and they freeze pretty quickly (can be unusable in under an hour). My only negative would be that they do also warm up after not too long (however, as these are the only teethers that hell use, I cant knock off a star). Plus, in this set you get four, so you can have a few in the freezer at once to throw into the rotation. I think he likes these because the material is pretty soft and light (even frozen), and both the hands and feet are easy for him to hold and turn around on his own, though not too big as to be uncomfortable for him.

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 Channels

The 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 bearing

The 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 pads

Integrated 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

  • Low-Noise Adaptor (L.N.A)
  • NA-YC1 4-pin PWM y-cable
  • NA-EC1 30cm extension cable
  • 4x NA-AV1 anti-vibration mounts
  • Fan screws
NF-A8NF-A8

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.
