I have been wearing these tops since November 2022, for a 74 year old my back is already a lot better, I appreciate the improvement, tips on how to wear them, I've even taken up maintenance gymnastics again, I've already got two and I'd recommend two more in the next few months, don't say it's not effective, be patient, medication doesn't work immediately either, I'm an example of that, so be patient, thanks Percko
