These are great beanies. I have 2 and they are both pretty as well as functional. Very warm for daily walks. Not too big or small--a nice amount of slouch. Love them!!

Ex Input:
These cartridges are a great alternative to the OEM at a fraction of the cost. The only downside is you are guessing at what color you are opening unless you find the sticker of what color it is through the yellow bag that they are each individually packaged in. The shipping box is solid and the foam fits great. All 4 are in one box and arrived perfectly.

Ex Output:
4

Ex Input:
The directions were so small you need a magnifying glass. Only using as a once use alarm so I can't comment on other features. Just like that it resets daylight time changes and when electricity goes off
