Come on Recteq! The power cable supplied with this unit is low quality Chinese made junk. How about introducing a non pvc cord that we can use in cold climates!!!!
all about making a extra buck? Ridiculous.
Honestly, trying to be serious and respond to your concern, what kinds of problems are you experiencing with the power cord, especially those that show up in cold weather?
It might be possible RT has recently changed the type of power cord they use, so your experience may be different than what others have seen so far.
While I've used my RT-590 in 15-20 degree weather and had no problems, and some others seem to have similar experiences, doesn't mean your concerns aren't legit. We just didn't have any specific info to understand what issues you experienced and perhaps offer some helpful suggestions.
Also, welcome to the Forum! Hope you stick with it, and I really think you'll come to enjoy your RT-590.
