Once you start using this bottle, you will have a hard time sleeping without it!
Got this after receiving a recommendation for an external warming device for camping in near 20 degree weather.  I tried it out at home first and learned several very important things:  Your bed retains warmth even after your spouse moves it, it stays warm over 24 hours if buried in a heavy down comforter,  if the water is scalding hot then it generates an amazing amount of heat for many hours, and it is the best camp buddy.<br /><br /> Well camping in 20° weather recently, I filled this up with 140° water and threw it in my 20° sleeping bag. I normally use a Reactor liner, wool socks and a knit cap plus fleece PJs. At 2 AM, It was way too hot.  I sleep cold and this was literally the first time I had to remove the liner, my socks and air the sleeping bag out.  I actually thought I was suffocating from the heat.<br /><br />Does it work? Will you kick yourself for forgetting it when you go on a business trip and have to stay in a hotel for several days? Will you wonder how you got along without it all these years? Will your spouse complain it is too warm in the bed?  Will your child ask for his own bottle because it is so nice in bed?  Will your spouse laugh that you were giving a five star review for a hot water bottle?<br /><br />Absolutely.<br /><br /> I never give five stars unless it is really useful. It is really really really useful.<br /><br /> One minor issue, I noticed that the knit sleeve is starting to tear. It is only been two months so not sure how long it will last before I have to sew it or try some repairs.
