Phoozy has been a game changer in the winter! Battery life lasts all day in sub-freezing temperatures.
If you can get this pouch for a heavily discounted price then maybe it's worth it. The pouch fits my iPhone SE plus a slim case just fine. Otherwise, the case doesn't seem to do much better than a thick wool sock which is probably better at insulating.
I tried it only once, so far, It worked ..
does everything I need (keeps my phone warm) and all for an outstanding (in a field?) price.
This is been great for my husband who works outside I actually bought two. That way I could put one inside the other and it works really well when he’s out in the woods cutting trees. Thank you very much!!!
