Very good, hopefully it'll help long term
GO 2 was kept in place snugly and this worked better than the adhesive pads. Easily stays in place if under a tee shirt and more convenient to remove when going to the gym/showering etc.
Easy to set up but it does need calibrating quite often. Easy to wear, and does what its supposed to do. Feel like I'm standing straighter already! Seems to need to be charged everyday though.
