I use the tub regularly for myself, husband and clients. It’s simple, easy to maintain and the customer service is 5 star. Doug is the best and really takes care of you when you have questions! Hands down Best investment I’ve made all year…I feel more supported and resilient dipping regularly then ever before and am really glad I went with Edge Theory labs over other companies because they truly walk their talk and are sharing positive, powerful ways to plunge!
