Nohtaram Posted October 29, 2021 Share Posted October 29, 2021 Hi guys, I have chance to buy Ultrasonic sticks for less than half their retail price. As I need new sticks this would be a great option but I'm not sure about their durability. I found couple rewives and opinion are mixed. Both US and 2S Pro are known for spliting Ergo Spine in some cases. Can users of Ultrasonic sticks share their perspective? Quote Link to comment Share on other sites More sharing options...
