The angled AC outlets on each side are a genius decision and the unit feels quite secure once inserted into your wall. I bought this for my husband and he actually uses it! If they were my only pair I?d been a tad more disappointed. "NewItem". I spend 3 seasons out at my firepit and the 4th in my garage. Without me even asking them to fix it. I have this strapless slip on under all these dresses to give a cleaner and solid look to this dress. They are a perfect fit. 5 to test the theory but my feel were flopping around inside these. I think the problem may have been the strange way they were laced up when they arrived.
