Not good at all. Other than that, they seem to fit my boat well Woot! Heavy duty 6’ non-tangle wire. We ended up spending 5 more hours out sight seeing and shopping and my feet still feel fine. )WARNING: I got this for a Nissan Rogue. Because the weather is so nice, I sit outside. Mostly I wanted to never have cold feet or ankles, but not have sweaty feet either. Now, the controller itself is ultra comfortable and light. Id highly recommend this especially if youre on a budget.
