Sharper Image Mini Vintage Refrigerator Heating Element

I've been using these for a number of years and know of no better reusable solution. I've gotten eight of them over the years and had only one fail when the heating element stopped working. When used with an air tight case, they only need to be recharged every couple of months. I use them in some file cabinet drawers so these need to be recharged weekly. Note that they do heat up when they charge so it's wise to recharge them when you can keep an eye on them and not let them sit overnight unattended.

It makes the image sharper. It seems to be very high quality optically.

our refrigerator is covered with them!

Having procured a sample of this lens before B&H stocked it, I have been shooting it on the s1R Lumix. Painterly is the best way I can describe it. I own the Lumix 85mm and 50mm F1.4 and this is a different beast. Closest lens to this was an old Wollensak 360mm set on a Sinar 8x10 P back in the 80s' that I played with ( it lacked color saturation however). The saturation on this lens is great and the merger of contrast and color is more like a artists paint brush in detailed areas. Definitely a lens with 2 different characters , one wide open and the other much sharper at f8 to f11. Even with the sharper f stops the character is unique and saturated with a vintage lower contrast look. The absence of ED glass and aspherical elements may allow a confluence of micro rainbow aberrations within the elements and probably contribute to the character. Rembrandt lighting in portraits would be interesting. A good lens for play or serious work especially creating vintage still-lifes at 180mp on the S1r.

Have a high end refrigerator that is plug in into it, so far so good!

It was time to upgrade and this camera is definitely a good choice. Much brighter image and sharper.

Use it to not only protect the Lens but it also cuts out the haze making a sharper brighter image.

Does not degrade image quality which is important. Protects the front lens element.

Even better than promised. Will try hooking it to my refrigerator.

Strong enough to hold up a refrigerator, I think. Fits perfectly, of course.
