Example Input: Great for recessed or track lighting Dimmable LED White to Color. Doesn't produce Green and Cyan well but other colors are good. These also come in PAR models also (with pins on bulbs) For table lamps I recommend the A19 Hue models for a natural look.
Example Output: 4

Example Input: This hand exerciser is just what I needed since slightly injuring the muscles in my hand . Just by squeezing the metal coil I can feel it helping to flex that muscle. It's like instant therapy.
Example Output: 4

Example Input: I like the pages and the layout. The problem is if you have to carry it around much the outside cover deteriorates quickly. After just a week or so mine is coming off.
Example Output:
