What temperatures are you running these in and how long does the battery last? Also, how was the fit? They are obviously direct from China, rather than manufactured for a domestic supplier. Recognized by the poor English translation.
Thanks.
I only ran them in 40 degree temps for 1 hour. Therefore, I can not tell how long the batteries will last on a charge. I like them, they have good reviews on Amazon, and free returns if you do not like them.
