question:
This is easy to use and comfortable. The heat doesn't last that long and the scented smell is so terrible that I can't even keep the eye mask on that long.
answer:
negative

question:
Look out. I've used these for several years and the colors are no longer red, dark blue, yellow and dark purple. I received neon green, orange, aqua blue and fuchsia pink. Dark purple was okay for my little guy, but bright pink isn't going to work. Will either have to use one old car from last school year or order another set to have four. I put two under a yumbox and two on top in a lunchbox. Others are right about not staying cold long, but works great to keep non perishable items cold.
answer:
positive

question:
This printer continues to print poorly. I've aligned and cleaned the heads, changed the cartridge etc. Far cheaper printers print much better than this. It's a disaster. It's going in the trash if they'll take it.
answer:
negative
